to put old firmwarwe back on ur iphone go to google and search for “iphone firmware download”. download it to a aplace u will remember. Go into itunes and (if on windows) hold shift, and click on restore. find where u downloaded the old firmware to and click on it. It will erase everything on ur iphone but if u backed up before u did this then it shouldn’t take long to get ur apps and stuff back. u might want to take screen shots of ur iphones app pages. to take a ascreen shot, press the sleep and home button at the same time. once u got ur apps back and u’ve downgraded, go to spiritjb.com and download spirit. its an untethered jailbreak for any ipod/iphone on any firmware.
oh to restore on a mac, follow all of the same steps and instead hold option and click on restore. the rest of the steps are the same
