    Hey fellow Bhatters!

    Anyone here know of an easy way to downgrade and jailbreak an iPhone 4.2.1? I searched Google and tried a few ways only to have to wait 25 minutes to restore my phone back to factory settings...any help will be appreciated.

    Thanks in advance :)

    Hey, I am pretty sure you cant downgrade a firmware once it is upgraded unless you saved shsh files from the previous to a 3rd party server (I forgot the name). However according to the greenpois0n readme it does firmware 4.2.1. Goodluck.
