i hope you didnt buy it,
I got one and have had absolute nightmares with it.
MMS cannot be recieved,
tethering is very hit or miss.
Ive done everything humanly possible to get it working, i even flashed an international developer version of WP8 onto the phone!
All that managed to do was fix some of the MMS problems. Still cant recieve them from Wind mobile users.
Tried the access point app, still nothing.
I gave up, i put the rogers ROM back onto the phone and put it up on ebay. No pentaband phone should require that much hassle to get working.
