What kind of antenna will the Bold have? The specs I can find state that it will have the following:

UMTS: 2100 / 1900 / 850MHz, GSM: 1900 / 1800 / 900 / 850 MHz, GPRS, EDGE and HDSPA networks

From what I can gather, T-Mobile uses the 1700 MHz band for its 3G network. Will they be releasing a separate 9000 for T-Mobile, or will the soon-to-be-released version for AT&T be compatible?

yes you are correct about the antenna right now...

as for the tmobile one, no one knows yet what they are doing for it

So T-Mobile will need to release a separate model for their network. Is that what you are saying?

yes, because the radio frequncies will need to be changed

Kinda negates unlocking and using on another GSM carrier's network too, doesn't it?

Not just one band. T-mobile has two frequents 2100mhz and 1700mhz bands for 3G network.

Right, one for upload, one for down, but it needs both.

I was thinking the same thing Dubdub. Hoping to pick up an ATT Bold and unlock it. Not that it really matters, I suppose, I'll probably have another phone before T-Mobile ever gets 3G in my market anyway.

this could mean we could see a 9band device soon! 4 edge plus 5 hsdpa
