Hi, i need a little help here..
My phone just got back from NCC, and now the right speaker isn't working anymore!

I tried playing music and close the left speaker with my finger,
and there's no sound coming out from the right speaker!

The FM transmitter option is also gone, but then i enabled it with fmtx faker...

Is this software or hardware problem? I really hope it's software though.. i don't want to leave my phone for another week
