http://discussions.apple.com/thread....sageID=9330312 ^^Thats just a thread with more people with the same unresolved issue. Ok about 3/4 of the time when my battery is below 30% I will lose service to my phone entirely. I will have to bring my phone back (wake it) for it to find serivce and bring in my messages that I missed. I have replaced my phone twice (about to be 3), my sim card once, new case, new screen cover. I've set up a new phone, set up from backup. I did backup on old computer and the new phone on my laptop. I have stumped so many Apple "Geniuses" with this and am losing hope. I have a new iPhone coming in tomorrow. Does ANYONE have any advice at all on what this is or how to fix it?
