Hi all. First off, I did search but haven't seen a problem that's exactly like mine AND I kind of need to get this problem taken care of as quickly as possible as I have a series of important conference calls this afternoon that I can't miss. Today, all of a sudden, I'm dropping calls left, right, and sideways in areas where this has NEVER happened before (my house). My mom also said she heard very weird noises coming from my end of the line at a time when I wasn't even talking--she said they were ghostly-sounding garbled talk. I'd also recently noticed decreasing battery life and so was considering restoring as new but I'm a little scared I'm going to lose all of the hard work I did in jailbreaking and customizing my phone since July. So I guess my questions are as follows: 1. Does this even sound like a problem that a restore could fix (or at least improve)? 2. Are there still issues I need to worry about in terms of restoring and re-jailbreaking? I have a 32GB 3GS and it's still running 3.0.1 because I was afraid to upgrade. 3. It also has a crack near the headphone jack that I've let go because I didn't want to raise a ruckus over something so minor, but now it appears that the two sides of the crack are shifting a bit, like one side is now higher than the other side. Should I just restore and wipe out all trace of the JB and take it back in to Apple? 4. Sigh. Thanks for all of the help, everybody!
