My iPhone 3g i bought late 2008 (november or october, i can't remember) is not opening any application. it opens the ones Apple made such as contacts, phone, ipod, safari but it doesn't open any of the ones i downloaded and paid for in the iTunes store. should i go to an Apple store or is there a fix?when you try to open an application and tap on the icon (an application which is not native with the phone, downloaded with itunes) it crashes to homescreen. i restarted it and everything by pressing power and home button at the same time etc...
