This phone appears to have the necessary radios to handle T-Mobile 4G at 1700MHz (makes sense since it's marketed as a T-Mobile 4G phone). But it also is indicated as having the ability to operate on 850MHz and 1900MHz, which are AT&T 3G frequencies.
Does this mean that an unlocked Exhibit II 4G could be used on either T-Mobile or AT&T? That would be kind of nice.
How do I get rid of the "double" numbers on the exhibit II. I keep my phone numbers on my SIM card and when they put it in my new phone it copied them to the phone and now both are showing when I bring up my contact list.
