i dont know if its this latest update or what but my iphone is crap now. it'll do everything from go to the home page in the middle of internet surfing or writing a text or it will just turn off where i have found out i have to hold the home button and the power button for it to come back on. Today it told me i didnt have a sim card in it!!! WTF! my friend said i should go to settings and reset my network settings so i did that....now i cant use the internet cuz it wont pick up EDGE. what the hell is wrong with this thing?
