the holidays have brought to my attention some problems with call quality. i live in chicago and get great signal, but my calls are always distorted. as soon as it starts ringing it cuts in and out a bit with digital breakage. like i had zero bars and made a phone call from a basement. i had to enter a replacement creditcard number on an automated service and even after 6 tries couldnt get it in because of the distortion. calling cust. service, i couldnt understand them clearly. real bummer. ive used the regular handset, wired headset, bluetooth, speaker, all the same. i tried flashing the new radios from XDA but it didnt make a difference. ive even SBF'd (or equivalent) when playing with wallet. i'm seeing a lot of people having similar issues online but like they say, happy customers dont post that often. should i be taking it back? am i getting a refurb now? i'm in it to win it with this phone and want to be happy, but this part i'm struggling with.... advice?
