iPhone 4 Possible on T-Mobile? Need Someone With Tech Understanding To Clear This Up

Is it possible for the iPhone 4 to get 3G speed on T-Mobile's network? We'll need someone with technical or expert engineering skillz on this one.

Towards the end of the WWDC 2010 keynote today, I kept hoping Steve Jobs would tell us about this "one more thing" in stored for us. That one more thing being that the iPhone 4 is coming to all the other networks in the US. At the very least, given that T-Mobile uses GSM as does ATT and my current network, I had hope that to be the case.

No go. The disappointment was not as acute as the Lakers loss last night but it weighed in me a bit into the afternoon. So this is what I tweeted:

iPhone: no iPhone for T-Mobile...sniff, sniff, sniff...AT&T, guess I'm gonna have to be your bitch...

T-Mobile tweeted me back about myTouch Slide. Right. iPhone 4 or myTouch. I am not that stupid.

So I trolled the Internet for more details and I came across an interesting comment about the iPhone 4 and T-Mobile's HSPA+ network. A couple of things happened.

On MacNN, the FCC page for iPhone 4 stated it is now a five-band phone. Penta-band? Anyway, none of the frequency is the 3G frequency used by T-Mobile's 3G network. 1700Mhz.  That's the end of the story, ain't it? Well, maybe not.

And this is where we need someone who knows what ins-and-outs of 3G technology and how everything works.

Over at TAUW, I read a post about the iPhone's new world-phone ability.  It's the exact same topic as the MacNN post except, now, read the 3rd commenter.  An astute observer no doubt who pointed out that the new HPSA+ network currently being deployed by T-Mobile in select markets but will be coming to more than 200 million users uses many of the frequency supported by iPhone 4.

The evidence is the Web Connect modem being sold by T-Mobile, which supports 850, 900, 1800, 1900, and 2100Mhz.  No mention of the current 1700Mhz that the current T-Mobile 3G network is running on.


And the iPhone 4?  It supports 850/1900Mhz in the US and 800/900/2100Mhz in the internaitonal realm.  Like the reader, MacNN pointed out the lack of support of the new iPhone 4 for 1700Mhz but not what the T-Mobile HPSA+ network and iPhone 4 both support.

Does this mean anything?  See why I am hoping someone with wireless engineering backgrounds can help us out.

Will the iPhone 4, officially or otherwise through unlocked means, support T-Mobile's fast 3G network?  Does this also mean that the iPhone 3G and iPhone 3GS will soon run on T-Mobile's 3G network?

If this is the case, there could be another positive possibility.  That being that the iPad will also run on T-Mobile's HPSA+ network as well.
