Selling iPhone 4 question

[Gary86]

I'm eligible for a full upgrade according to AT&T and plan to use once the iPhone 5 comes out. I'm on 4.3.3 now and jailbroken. How do I restore or wipe the phone so I can keep it on 4.3.3 so the next person can jail break it?

Thanks

If you have your SHSH blobs saved at 4.3.3 (you probably do if you ever opened Cydia while Apple was still signing 4.3.3) you can download that ISPW and restore to it. iClarified is a good site with tutorials and download links.

I agree. Restoring it (and jailbreaking it) with a good, untethered method will be the way to go.
