I want onto Rock today (my usual jailbroken app service) and i found this app called Overboard which lets you have a look at all of the pages on the springboard. It says I must be on Cydia to download it. I exited and went to Cydia. After I click it, It says: Loading Data with a loading fan above it and then it just exits. I then went onto blackrain and reinstalled it. Still the same thing. Any ideas what might be wrong?
