I have been having problems recently with my 16 GB 3G. The display slows down or doesnt work at all. When I swipe form one page to the next, it hangs between pages. Games slow down or hang entirely. I have had problems with the iPhone searching for cell signal or showing No Service, even when the iPhone next to me has 4-5 bars. Restarting will get the signal back. Restarting my phone will solve the problem for a day or so, but for the first 9 months I owned this iPhone, I didnt have these problems. Last 2 months have been problematic. Genius Bar suggested that I restore the phone to factory settings and not from backup. I did, but the problems I mentioned still exist. Genius said that I needed to reduce the number of apps (all 9 pages were full), I only have 3 pages now, but no change. I have maybe 6 gigs of music and video, and 30-50 photos at any time. I don't have any apps besides Mail that 'checks in'. I rarely have more than one internet page open. No alarms in the background. Bluetooth is active for the car connection. This phone is perfect no scratches, no light leaks, no dead pixels, no cracks, no dust and if the choice is restarting every day or getting a problematic refurb, Ill just restart. If the RAM is corrupt, then Ill switch iphones. So my question is, how often do you restart your iPhone?
