What's going on guys, need some help. iphone 4 GSM running 4.3.3 jailbroken, my phone was running slow so (as I have done many times before) I restarted the phone from sbsettings power option. The phone has been stuck at the apple screen ever since. I did not install anything new from cydia today or yesterday, I did update mywi today but that did not cause this at the respring stage after install so I am not sure why this happened. Any suggestions?
