My phone started acting really wonky today, but most of the major issues seem to have passed. Now the annoying thing it doing is taking like anywhere from 5 to 15 seconds to wake up when I press the power key. I'm considering trying a couple of things, and wanted to get some feedback: 1. A factory reset, but I don't know what all will be involved in getting it back to the state where it is now or what I may lose. I do have Titainium Backup and My Backup Pro. 2. Calling AT&T and trying to get a warranty replacement. It is still under warranty, but I'm kind of afraid of getting an older refurb that would have the shutdown problem or something. Is there maybe something else I can try?
