Anyone mind to tell me *WTF* is this Hash Sum mismatch BS, please?? For the past 4 days, I've tried downloading in Cydia, this error constantly popped out and killed the downloading process and I really hate it to the point I almost threw my iP4 at the wall.. !!! Someone help.... I thought it was just a glitch and would go away, but unfortunately, it's still here. Additional information: Factory Unlock iP4, 4.3.3 JB'ed with Redsnow.
