How to upgrade a jailbroken ipad
Hello again everybody, i have just recently jailbroken my ipad with redsn0w, my ipad right now is jailbroken and is thetred and its version is 4.3.4. I read the guide to upgrade a jailbroken device in this forum but as i'm not english i didn't understand a lot of things, plus that guide if i understand correctly was about snowbreez but i used redsn0w so i didn't know if i could apply the same process. Another weird thing that i could never understand is that in that guide is written that i need to sync my ipad, i actually syncronyzed it just once at the beginning and i noticed that it deleted all wjat i had in my ipad and out all i had in the computer in the ipad and i was wondering if there was a way clicking on the sync button to copy not transfer all apps, music, movies etc. On the computer without deleting anything. Another thing is that in the guide there was the method with a paid app from cydia and then there was written that it could be done even with free apps but i didn't understand which app. Could anyone be so kind to explain how do i upgrade my ipad(jailbroken with redsn0w, 4.3.4 thethred, 64gb no3g) in easy steps? Thanks everyone.
P.S. I may have alredy written this but i cannot find it anywhere, maybe something went wrong when i tried to submit, if it's somewhere then i'm sorry for posting this again.
