I noticed a problem when using my iPhone 3g. This has happened to me three times already. It seems that my iPhone 3g randomly restarts itself when using applications. Is there a proper way to exit an application? because I just press the home button to exit an application. Not sure what's happening. Maybe I'm overloading the iphone's memory and causing it to restart? is that possible? The last restart happened when I tried to open the phone saber application. Not sure if it's that program specifically but I'll definitely try to keep track of the programs that cause my iphone to crash. anyone else experiencing this or have a fix?
