and you have to restore the whole damn thing because you want to update the firmware, can you download the app again for free? and who gets the credit card information, cause after all I trust Apple more with my credit card info than some hacker
When you click purchase you will be asked to sign into Cydia using your Facebook or Gmail account so that if you need to re-download you can do so. It means allowing Saurik's server to see your password, but I'd trust Saurik before I'd trust many companies. And really, what interest does he have in reading my email?
