I have an iPhone 3G and with iOS 4, it's slower than it ever has been, especially when Jailbroken, but I'm not about to Restore my iPhone to get rid of the Jailbreak either. I want to downgrade to 3.1.3 but I did earlier this month and I couldn't Jailbreak it with Redsn0w 0.9.5. I want to keep all my contacts, Cydia data and a way to Jailbreak my iPhone 3G while on 3.1.3 with Redsn0w with features like custom boot & recovery logo, battery percentage and, if it works on 3.1.3, Multitasking with Multifl0w. Has anyone got a solution as to how I can do all this? I do not want to lose my important contacts for the 16th time because my backup for 3.1.3 doesn't have the contacts I currently have now.
