I got my iPhone 4 last Thursday and it came with couple annoying defects, as you probably all heard (yellow blots, reception problem) Nothing is more annoying than when I pull my iPhone out of my pocket, it's turned off. Or as I was teaching piano lesson today with my iPhone visible in sight, it decided to reboot all by itself for some reason (during lesson I comically said,"my phone is acting crazy"). There is no way that it is accidental button hold. It must be some kind of software glitch. What is going on?? Is this just me?
