    Is it possible to get 3G Data with iPhone on Tmobile using the Simunlock? I'm getting conflicting news on it. Would like to know as my company is forcing everyone to switch to the T'Mobile....

    See how it plays or do not; the fact that you can't get USA T-Mobile 3G data on it won't change, though.

    just curious. Isin't T-Mobile using the standard 3G Spectrum. What is limiting T-Mobile's 3g data to work with the iPhone?

    It won't work. Some read up from another site:

    Apple used the Inferion BGA736, a 3 Band (800-900)/1900/2100MHz chip.

    It is missing the critical 1700MHz band that would allow it to work universally on the U.S. carriers 3G networks. So you will be able to use the 3G portion only on ATT, and in Europe. But that would not stop you from cracking the 3G iPhone and using only EDGE on T-mobile’s network becuase it would still need EDGE radio to fall back onto on ATT’s sparse 3G network.

    As for visual voicemail, I doubt seriously that you will see it working because this requires an upgrade on the carriers and of things. And why would T-Mobile spend money to support a feature on a phone they technically don’t support. Now T-mobile in Europe does sell the iPhone, and has visual voicemail but again why spend the money here.

    There isn't one standard 3G spectrum. There are fourteen so far, although multi-band devices that support the ones AT&T uses in the US and the ones most commonly used in Europe cover a large majority of the developed world.

    http://en.wikipedia.org/wiki/UMTS_frequency_bands

    T-Mobile uses a different band than AT&T, with which most multi-band 3G devices, including the iPhone, are not compatible.
