Summary: Hit and miss. If it hasn't been updated by the previous owner, then most features will be out of date and won't work. If it has been, then BES and the antennas will function normally. Kinda not worth buying anymore though, especially on Sprint.
Summary: Avianna LLC is an incredible seller. The phone did take a while to get to my place however when the phone didn't work on my provider, Andrew stayed on the phone with me with tech support with my service provider for over 1.5 hrs just to try and get the phone to work.
