BBM not working, can't make calls and apps only working now and then.
I've had my phone for well over a year now and I haven't had any issues with it. Recently however, my BBM was the first thing to stop working. After this, my other apps only decide to work now and then. I also can't make outbound calls anymore. Nothing works with/without Wi-Fi so it's not a contract issue. If anybody could shed some light on what's up/ways I can attempt to fix it that would be great, thanks.
EDIT: Sorry I didn't realize there was a 4S section, my phone is a 4S.
