Summary: I had two of these, unlocked, and had to send them both back because they would not hit on T Mobiles system. Several different T Mobile reps indicated their best guess was that the phones were not really unlocked. I ordered a BB Classic through T Mobile and it is a great phone.
Summary: i put in a sim card in when i got the phone, and it told me to put a sim card in. the wifi doesnt even connect on the phone. not really sure what i paid over 50 for besides to say that i have a blackberry
Verizon branded phone that does not work correctly on AT&T's network. Beware.

Summary: Received a 9930 that will not work correctly on AT&T network after multiple attempts. Only gets EDGE signal and does not get a good quality signal half the time and consistently switches between trying to connect to CDMA and GSM.
Summary: unlocked my ass. wasn't able to activate it, went to an AT&T store to have their technicians activate it and neither they nor their online customer support team; instead they report it was a Locked Verizon model; i would have appreciated this information before as i'm Sure there are Some Verizon...
Summary: This is not an international version and neither is it completely unlocked. Whilst you can make and receive calls this phone is primarily for Verizon in the US and you will have problems connecting it to the Blackberry Internet Service if you are not in the the United States AND with Verizon.
