Guys, i owned non-jb ip4, everything ok excpt the home button issue which very annoying and unresponsive,but my question is.. is there any of you guys experienced the problem same like mine which occured on last saturday night,where i went to sleep and the phone still fine with batt. around 75%.. But on sunday morning, i woke up and realized that my phone date and time go crazy, like reset or something. Any clue what happen?

I think that was the on/off button .. The button abit loose
