if you are having problems, do a DFU restore, and setup as a new phone

Did that... It had major problems the first time then I restored it n now it's doing this

Do you realize that "setting up as new" means you DO NOT restore from a backup.

If ya ask me....restoring from a backup does almost nothing. You must restore and setup as new to truly apply trouble shooting.

Is it not also true that when you made a backup in let's say ios 4.1 and you update to ios 5.1 then the 4.1 backup will not restore on the 5.1?

Backups are forward compatible. If you do a backup on an older firmware you should have no issue restoring it on a newer firmware. The issues arise when you try to restore a backup from a new firmware onto an older firmware.

Although, like Zig I would recommend always setting the device up as new since restoring a backup can cause issues.

Could it be that when I made the backup my phone was jailbroken that being the reason I got an error restoring it on the newer firmware?

I don't know. I have never heard of anyone restoring to iOS 5 from the backup file of an iOS version as old as 4.1

But have seen countless problems from people restoring to iOS 5 from an iOS 4 backup, only to have to restore again, due to unfixable problems.

I don't know i iTunes would or would not allow the restoration of a 4.1 backup to iOS 5, but regardless it is just a bad idea plain and simple.

I just used 4.1 as an example.But thanks anyway for the answers

Well what I ment to say is wen I first jail broke it, it worked good a couple weeks. Then it started really messing up. So I then hooked it to iTunes and did a data reset and downloaded iOS 5.1. It completely erased everything n made the phone like new. Then I rejailbroke it again. I did not restore any old files at all... But now this time the battery life has really gone bad and the speed it's glitchy and slow
