Of course you can downgrade your iPhone, iPod Touch or iPad from iOS 5.1 to iOS 5.0.1 or iOS 4.x.x. However, if your device has an A5 chip (like the one in the iPhone 4S and iPad2), then you will not be able to downgrade your device.
For those of you who have iOS 5.0.1 jailbroken, and are interested in keeping their device jailbroken, we do not advise you to update your operating system to iOS 5.! Up to this point, no jailbreaks are available for iOS 5.1.
If you are one of the lucky people who can downgrade your device whenever you feel like it (this means you have either an iPad 1, iPhone 4, iPhone 3GS, iPod Touch 3G or iPod touch 4G) we can help you downgrade your device.
