9860 work in 3G mode on AT&T. I see the frequencies have some compatibility from 2G to 3g but before I shell out $500 I need to know for sure that it will work here in the US.
sorry for the question. I did some research on network frequencies but nothing that said "sure buy it it will work-on GSM but only in 2G mode"
is there an easy place to go to do an unlock?
thanks for the reply-

Mine was branded Rogers (same frequency as Telus) and I used blackberrycodesource.com to unlocked it, was very easy and fast... My carrier is Tigo here and I have H+ signal and uses 850Mhz and I think AT&T's 3G/H+ is 850 or 1900Mhz and this 9860 support both...
