Hello all, I have a JB iPhone 4 running 4.1 and certain apps are crashing quite often. Apps like iFile and iHeartradio to name a couple. I go to open them up and they open just fine but then they crash after about two seconds. The only way I can get them to run is to reboot the phone. I've tried freeing memory in two different ways and resprings but only rebooting works. This is getting frustrating. Any thoughts on what may be causing this? Thanks for any input
