I have owned an iphone 3G and iphone 3GS and now have upgraded to the iPhone 4, and the new one is making way too many calls on its own! Not only is it making calls, but I also find it going down the list of ringtones in my settings, or turning on Pandora, or opening Radio Wunderground and playing a station. I never had these issues with my older iPhones. Does anyone else have these issues? I even checked the settings to have my screen lock after just one minute and I still have just as many problems with this! Very frustrating! Its as though the touchscreen is waaAAY more sensitive? I dunno, any insights would be appreciated!
