Okay so I'm running regular old 3.0 firmware (that was [POPCORN].) And my device IS jailbroken (fyi: with redsn0w). and I notice some of Cydias apps screw up on 3.0 and arent built for it. Like I [POPCORN] Mewseek pro and its not working on it. Should I downgrade to 2.1.1? I want to have stable apps that work. [POPCORN] or not.
