Interested in jailbreaking your iPhone, but wondering if it’s safe to use iTunes and/or the App Store after you’ve done the deed? Worry no more… You will be able to continue using both iTunes and the App Store after you jailbreak your device.
You’ll also be able to start using Cydia, which is essentially an App Store for jailbreak-related apps. So go right ahead and jailbreak your device. Just don’t let iTunes update the OS on your device until the new version has been jailbroken.
