Back in the early days of Engadget, everyone -- including us -- thought mobile virtual network operators (MVNOs) were totally poised to be the next big thing. And why not? You get to be a wireless carrier without having to operate your own infrastructure (which is by far the most expensive, difficult part). Just what the doctor ordered for the big, stodgy wireless carriers, each struggling to balance differentiating themselves while trapping their customers in their walled content and services gardens.

Little did we all know that the differentiation most of these MVNOs had in mind was slapping their lame brand on some existing phone that people could get sooner, cheaper, and often with a better plan on one of the major carriers. Even Helio, the one MVNO that managed to keep gadget nerds' attention for more than 30 seconds, couldn't ride the Ocean to the land of success, writing off its half-billion dollar 2.5 year run for $39m in Virgin Mobile USA stock.

Let's take a look at the last five years in dead American MVNOs. For a graveyard of well over billion dollars, you'd sure think it wasn't so damned shabby.

Amp'd Mobile
Began service: December, 2005
Ended service: July, 2007
Network: Verizon
Amount invested: reportedly $350 - 400m+
Backgrounder: Despite backing by MTV and Universal Music Group (and a ton of VCs), CEO Peter Adderton managed to run this MVNO straight into the ground in little more than a year. It didn't help that the people running Amp'd couldn't get thousands of their "customers" to make good on their bills, strangling what little income the company did have. Way to go. Amp'd's mobile content still lives on, though -- ever catch Little Bush on Comedy Central?

Of course, it all seems so obvious now! How did we not interpret El Jobso's true meaning of the iPhone kill-switch -- it actually kills you. We have noted iPhone expert Stephen Colbert to thank not just for this brilliant deduction, but also for sticking up for the lot of us and giving the iPhone 3G a cold staredown -- but not before declaring, "I knew I should have gotten a Zune! They can't kill me... or do anything else." Zing! Clip after the break (iPhone at 5:45).

After spending a few minutes with it, there's no question to us that the Touch Pro is HTC's most impressive handset to date (even if you count the Xperia X1). Okay, the phone is still a bit thick (roughly the same as a Tilt), and there's no 3.5mm headphone jack, but it's got a very small footprint and a very comfortably proportioned keyboard. We can also really definitely appreciate the lengths HTC is going to trying to make Windows Mobile a bit less doggish these days -- but were they to spice up the Touch Pro with a capacitive touchscreen and Android, HTC might just have a game-changer on their hands.

Well, judging by the dozens of tips we just got, it's time to once again get your Pwnage on with version 2.0.2 (which was released to counter the, um, "fixes" in iPhone firmware 2.0.1). As usual, hit up the read link.

Your morning iPhone news fix: looks like Apple's seeded a beta of firmware 2.1 (not to be confused with the supposed 2.0.1 that will fix the myriad bugs and issues with 2.0), which may have some new GPS features that would imply turn-by-turn directions. No argument from us if Apple really is including new Core Location hooks for tracking your direction and speed, which would both be needed for doing proper GPS navigation.

Another bit which may or may not make it into 2.1 is copy/paste. We're still both hopeful and skeptical, but supposedly in the new version of the WebKit framework exists commands for "plugins," "copy," "paste," "cut," and some others. We can't confirm if these really exist (and if they do, we don't know how they've actually been there, or if they're simply holdovers from the desktop WebKit frameworks), so don't hold your breath. Also supposedly making its first appearance in the 2.1 beta code: Apple's push notification service.

Oh, and by the way, if all this has whet your appetite for the device, sounds like today will be a bad day to try and snag one. Apple's retail site shows absolutely zero iPhone availability in the US, so if you're jonesing then check out eBay or the seedy looking dude on the corner with the overstuffed trenchcoat.

Update: Looks like the stores have been updated in the last hour, many have stock. Game on!

It's hard to think of any other device that's enjoyed the level of exposure and hype that Apple found in the launch of the first iPhone. Who could forget it? Everyone got to be a gadget nerd for a day; even those completely disinterested in technology seemed to come down with iPhone fever. But the original device was still far from perfect: its limited capabilities (especially in the 3G department), high price of entry, and the small number of countries in which it was available kept many potential buyers sidelined. Until now -- or so Apple hopes.

The wireless industry is a notoriously tough nut to crack, and it's become pretty clear that the first iPhone wasn't about total domination so much as priming the market and making a good first impression with some very dissatisfied cellphone users. With the iPhone 3G, though, Apple's playing for keeps. Not only is this iPhone's Exchange enterprise support aiming straight for the heart of the business market, but the long-awaited 3rd party application support and App Store means it's no longer just a device, but a viable computing platform. And its 3G network compatibility finally makes the iPhone welcome the world over, especially after Cupertino decided to ditch its non-traditional carrier partnerships in favor of dropping the handset price dramatically. $200? We're still a little stunned.

So now that Apple finally stands poised for an all out war on cellphone-makers everywhere, will the iPhone 3G stand up to the competition -- and higher expectations than ever? Head on over to Engadget for our full review.

Here she is, the iPhone 3G, captured on video. We went through a number of the new features on the device and in the 2.0 software release for you. Apologies in advance if you're looking for side by side speed tests, we spiked the on-camera test due to coverage issues where we're at. Video of the unboxing and new feature walkthrough after the break. (We should also have a bit more video shortly, so check back soon.)

So we heard from a very reliable source that mobile user interface guru Matias Duarte -- who you may know as the man behind the Sidekick and Helio UI / user experiences -- actually left Helio late last year to join up with Palm. Although no announcement was made, we hear he and his gang of designers jumped ship (well before Helio completely flooded) to take on the monumental task of designing the UI for Palm's next-gen mobile OS (aka "Palm OS 2.0 or II"). His resume online now lists him as "Senior Director, Human Interface and User Experience" doing "Something new..." since September 2007; we got in touch with Palm, who confirmed that he's now under the company's employ.

Of course, expectations should be pretty high -- Palm's only been promising this supposedly game-changing OS since around 2004, and the company's reputation and pedigree is (or at least it used to be) in groundbreaking mobile UI design. But this news also kind of makes us wonder: if they didn't have a killer UI and user experience team already in place and long-since working their asses off by late 2007, exactly how far along are they on this thing, anyway?

MetroPCS may not have the largest wireless footprint in the States, but they did take a jab at the larger two CDMA carriers by announcing their intention to take on any Verizon and Sprint customers ready to jump ship -- as well as any "compatible" devices they may want to bring along with them. Sprint already supposedly does this (although we've still yet to hear of it actually really happening), but the specifics of MetroPCS's MetroFlash seem equally unclear. It doesn't sound like they'll reprogram just any CDMA device that walks through their doors, though, just the ones they've had a chance to test on their network. Definitely kills the buzz (and the number of devices that can be ported), but a little open is still kind of better than totally closed, right?

Money-losing companies with interesting technology and a small, if rabid, customer base still frequently tend to sell for healthy chunks of change -- especially in the wireless space. Look at Trolltech, for example, the mobile Linux company that never really made any money, yet somehow managed to be acquired by Nokia for its talent and IP, which apparently carried a value of over $150m. We know Helio was burning cash on a whole 'nother level, but that doesn't entirely explain why SK Telecom was so absurdly desperate to dump their $500m investment. At a $39m acquisition price, SK didn't just lose its shirt -- it lost that, the shoes, and then the pants. You know, the pants with a half-billion dollars in them.

It ain't over until it's over, but we just got word that Helio store managers received notification this week that the axe is finally falling: (at least some of) the nationwide chain of retail stores will be shuttered during Virgin's takeover of Helio. As we've heard, "there is no 'merge' in this merger," so it sounds like after this year's big executive reshuffle, SK Telecom is bailing on their half-billion dollar enterprise a big way. No word if the fabled Ocean 2 will make it -- or if Virgin will even let Helio customers keep their phones.

Alongside Helio -- more or less the last man standing -- the great MVNO goldrush also dies. Unfortunate that besides Virgin and a few local and M2M providers (like Amazon's Whispernet), pretty much no one was able to make it work. Then again, no one ever never said making cellphones and running any kind of carrier was easy.

If you're apt to believe it, supposedly a regional HTC GM by the name of Kevin Chen flapped his lips about the first Windows Mobile 7 devices launching in Q109 -- so between six and nine months from now. We reached HTC, which had no (further) comment on the matter, but everything we've seen about 7 so far kind of leads us to believe that 7-based devices launching before next year's Mobile World Congress sounds a bit premature, even if that doesn't necessarily jibe with the MWg roadmap (which promised devices possibly even later this year).

According to some slides unearthed over at TreoCentral, it looks like the Verizon Treo 700wx could be an unlikely candidate due for the Windows Mobile 6.0 (not 6.1) treatment. Usually carriers like Verizon won't bother upgrading devices as old as these with newer versions of their mobile OS -- partly to induce future handset purchases -- so we'll have to remain a touch skeptical until such time as the upgrade really does launch.

There's still plenty of emerging details and news on the iPhone 3G kicking around, but here's what you need to know from the minor bits floating around over the past few days:

• Jobs also told NYT that Apple's acquisition of PA Semi was, in fact, intended to reduce Apple's reliance on third-party chip makers. Specifically, he said, "PA Semi is going to do system-on-chips for iPhones and iPods." So, guess that's that.
• Per the feature showing up missing on a number of Apple's international iPhone 3G product pages, iLounge compiled a list of carriers which may or may not planning on implementing visual voicemail. Vodafone in Europe, for example, will not have it at launch, and will delay its rollout until later this year.
• A video of a new iPhone beta build running on live hardware shows videos now in portrait or landscape modes, and includes video playlists. We'll take it.
• Although DT's iPhone page reads differently, German paper Welt has it that T-Mobile Germany will be selling it for €1 -- so basically free, not unlike O2's iPhone 3G launch in the UK.

Update: T-Mobile just made the German pricing official.

Yesterday we went over a few of the more confusing bits of the iPhone 3G launch -- and let's be honest, this launch is way more confusing than the original go-round. Of course, there were a lot of burning questions to be answered from the audience, so we got an AT&T spokesperson to weigh in on what's on your mind. The most surprising answer? Contrary to reports implying otherwise, AT&T pretty much categorically claims that no matter where you buy your iPhone 3G, be it from AT&T or Apple, you have to walk out of the store an activated customer.
