att Pearl 3g on Tmobile

[DrLouie]

If I unlock an att Pearl 3g, will I be able to use it on Tmobile? Will I only have EDGE data? What other issues do I need to be aware? Thanks

You will only get EDGE speeds.

At&t and T-Mobile are using different frequency bands and unlocking your Blackberry is simply making the device available to work with other SIM card.
Needles to say that the bands and hardware will stay the same and the problem is not with your device, it's something that only the carriers able to change.

Any way, At&t SIM card will eork with your unlocked Blackberry Pearl 9100 but the speed you will get is 2G (EDGE).
Some devices from other carriers, if unlocked - can work with AT&T SIM card to get 3G.
If you get a pearl 9100 that is originally was from Bell and unlocked it should work with At&t 3G.

Other posts are correct. You will not get 3g but 2g .. You will not see a difference for email and bbm on 2g.
