Worked like a charm! Just upgraded my sister's iPhone 3G from 3.0.1 to 3.1.3, keeping baseband 04.26.08 and the Ultrasn0w unlock. She was complaining that new apps don't work with 3.0 anymore. Couldn't be happier! Sun, 7 Mar 2010 15:41:35 +0000 http://www.ilikemyiphone.com/2010/02/09/download-custom-firmware-3-1-3-ipsw-jailbreak-activate-unlock-iphone-3g-3gs-mac-windows/#IDComment60206491
