Ok, i have an unlocked iphone that i am currently using on Rogers Canada. I am pretty sure that this is not due to the unlock, or is just my phone, but i cant hear a dam thing when im trying to talk to a person on the line!!! it is SO frustrating!! is there any solution to this problem?? ANY help is greatly appreciated.
Thank you for your time.

We should do a sticky on this topic, called like PROBLEMS WITH LOW SOUND IN A CALL?? ----- SOLUTION: TAKE OFF THE PLASTIC COVER OF THE SCREEN THAT CAME WITH THE IPHONE, ITS BLOCKING THE EARPIECE!!!!!!!
