my iphone 4 will not let me pull up apps when im at home, i cn reset the network settings and it will let me pull up one app then it crashes again. But when im not home it works fine, it started doing this on friday. Can anyone help?
Go into the network setting on your iPhone and tell it to "forget this network" then reset the iPhone (power off). Turn the iPhone back on and connect to your network. See if that helps.
Generaly, if you having odd issues I would recommend rebooting the phone. On a recent support call I had with Apple they recommended we have our users reboot their phones about once a week to make sure things keep working smoothly.
