I got a 920 model, in my area I get edge as they haven't updated the towers here. When i make or receive calls there is a annoying noise in the background. The noise is the same noise that happens sometimes when I receive a text in the car and my cell is too close to the radio. Rogers had me reset some settings on the phone and restore the phone to new on itunes. Neither of these worked. When I am on 3G the noise does not happen. Right now I am waiting on a new sim card from rogers to see if i have a faulty sim car. What do you's think, have you heard of this noise happening yet.. Do you think its my phone, my sim card, or the towers here? I made a call in the middle of the night last night to my voice mail, did not notice the noise. Then again around 11am and the noise was there again, so something is interferring some how.
