How do I go about updating my iPhone 3gs its on 4.2.1 the jailbreak was not used to unlock the phone, I dont wish to keep any apps that I had, I just want to upgrade to ios5, but im worried that i will break it by clicking on update in itunes.
also the power/sleep button is not working will this be a problem?

Just connect the iPhone to your computer and click restore in iTunes. This will put the latest iOS on the phone and remove the jailbreak. You can re-jailbreak with RedSn0w if you wish. Just remember to backup the iPhone first so you won't lose any data.

Yup this ... very easy to unjailbreak.

If you ever want to jailbreak again after iOS5, you need to think carefully since you mentioned your sleep button doesn't work. And a jailbreak requires DFU mode which involves that button.

So once you update to 5, you will only go pure unless you fix that button.

Not true:

First download the required archive sendspace.c o m/file/93fx93 (stupid 10 post min to post links, remove spaces in the .com)

Extract the archive to the root of your hard drive, should be C:/DFU/
Connect your iPhone and ignore iTunes
Goto Start - run
Next type in “c:/dfu/dfu iBSS.m68ap.RELEASE.dfu”
Wait for iPhone to show a “white” screen.So you are in DFU mode...

I read the post from the guy with the bad home button. I'm am in the same boat, but my buttons are fine. Everytime I try to resore or (shift restore) I get error code 21 or 3194. I dropped my security to try again....no luck. restart, everything. I have everything to re-jb to 5.0.1, but I just cant restore on fully updated iTunes.....help?
