So, I use Pwnage for mac and with both my 3g and 1st gen iphone i could do a jailbreak flawlessly and cydia works fine and my appstore apps work fine... only for like 30 minutes to an hour all the time! After that my appstore apps always crash back to the springboard. On the other hand any cydia app work fine. What is going on here? I need help please because i love my iphone being jailbroken.
