I bought an ipad from my friend which is jailbroken on ios 6. I want to add my own apps to it but when I connect the ipad to itunes to do so, my options are "Set up as new ipad" o "Restore from backup." I do not want to lose the jailbreak. If I choose "Set up as new ipad" will that then install ios 7 and update the ipad, causing me to lose the jailbreak? How can I get around these options to keep the jailbreak and also connect the ipad to itunes? Also should I install iLex Rat from Cydia immediately just in case something goes wrong?
