I have an iPhone 3g running iOS 3.1.2, Firmware 5.11.07, Unlocked and Jailbroken. My question is that whenever I try to pull up Cydia it comes up and says "Loading Data" for about 45 seconds and then just crashes. The only application I have from Cydia is Rock and that doesn't even work anymore! So, could anyone please help resolve my issue with Cydia? Thanks in Advance.
