(adsbygoogle = window.adsbygoogle || []).push({}); So as title says i have a iphone 4 on 4.3.3
I want to unjailbreak so do i back up and restore to normal 4.3.3 then update to 4.3.4???

Just Backup and Restore (it will restore to the newest firmware)

Yeah like what igthomas said then it should work fine again on newest firmware

Check out youtube

just a question: why do you want to un-jailbreak ? Need to send back phone to AT&T or something ?

No just dont like it , battery draining very slow

Go to cydia, download SBSettings, install it, swipe on the bar at the top on your iPhone where the bars are, a window should pop up, hit "processes", press free up memory and delete some of the apps that are there, this should stop the draining of battery and make it faster

Still drained...
Now ive uninstalled everything and its fine

Moved to iPod/iPhone/iPad Modding.
