so i got my 3G all fixed up with a new dock connector so I can charge the phone again. I bent that little tab near the "do not remove" sticker back to where it is touching the metal rim inside the phone after I had it bent wrongly after reassembling the phone and it doesnt make a huge difference.

sometimes the call is completely clear and other times it will be staticy on both my end and the other end. could I need an update on the phone to fix it? im still running 3.1.2 because i dont feel like re-doing a jailbreak. but should I just upgrade to the newest firmware and re-jailbreak it all?

here is my original post from the first problem i had after replacing the battery for a picture of the tab in question
