Hello and sorry if this was covered somewhere... I have a 3GS factory unlocked... 3.1.2 Used blackra1n to jailbreak/install Cydia. Cydia installs and updates fine, but after I install any application (I tried about 5) it gets to the part when it needs to Reboot, the phone becomes inoperable and has to be restored via Itunes. I need to run a few apps from Cydia and this is really killing me. Any advice would be appreciated!!!
