My iphone 4S was literally sitting on my desk with nothing plugged into it but it was detected in itunes over the wireless sycning and i was jailbreaking my ipod touch 4g and the second it went into dfu mode so did my iphone. Except i was not touching my iphone and there was nothing plugged into. I just repeated the process simply putting my iPod touch 4g into DFU mode while my iPhone 4s was connected over wireless sync to my itunes. I noticed it kicked my iPad 2 into recover mode as well that is also running iOS 5. except it was not even detected in itunes i do not think.... this is interesting... As soon as my iPod touch went into DFU mode so the iphone went into recovery mode, just sitting there with no wires connected. So be warned, this was not a one time thing, i just repeated it. Here are the instructions on how to get any iPhone out of recover mode! And yes it worked for my iPhone 4S 3 times in a row! http://www.geekology.co.za/blog/2009/08/getting-an-iphone-out-of-the-recovery-mode-loop/ Just a heads up guys!
