Daaaammmnnn...which phone do you have? Only takes about 8 seconds on my iPhone 4
Iphon4
It was taking 30 seconds but now it's way too long
I highly doubt there is a way of just adding/removing something that will fix your problem, as much of a pain in the arse as this might be, you would be best off restoring your phone using a backup from before you Jailbroke and doing it all again
MyWi cracked does this. Thats a shame.
I know because my brother had me get it for him on his 3gs, same thing happened.
Buy your apps and addons.
It causes the long respring?
I would do a full restore, the amount of time you spend finding answers to your problem, you could be done by now. I know its a pain to do, but that's what I would do.
