    Hi, 1st sorry if this has been asked before. I've seen various 'iPhone won't charge' but not this exact situation. As soon as I updated my iphone 4 to IOS 5.0 I am unable to charge via the apple usb adapter, Apple or 3rd party cables in any standard usb port. The iphone is not recognized in iTunes so I cannot restore or upgrade the firmware.

    Trick is I can charge using any of the of aforementioned usb ports if I attach a kensington battery to the iphone dock with the battery connected to the same usb ports above in a chain. It will also charge via an ipad 10w power adpater.

    I've tried the locking device and inserting cable thing, no joy, ditto with powering down and cold booting with the cable. Tried turning off all services (push/gps/data/wifi etc) to try and minimize the iphones power draw. Nothing.

    Been like this since the ios5 update months ago but now I can't get up to 5.1.1. Any ideas folks. Thanks in advance.

    If you backed up, have you tried a DFU restore via iTunes, before?

    I had tried with previous versions of itunes but whats nuts is I just tried it there with the latest itunes and its now restoring/updating to 5.1.1. Your a genius and I think I'm getting old. Been jailbreaking since the iphone 2g 1.1.4 days but I think I'm losing it. I'll tell ya when its done if its back to charging normally. Thank you so much :)

    @jeremyshaw That worked perfectly. Thanks again. Also extremely surprised at the performance at present of 5.1.1 versus 5.0 after jailbreaking. Gone is the lag which made my iphone 4 more like a 2g and more importantly its charging directly with the iphone cable without need for the external battery. :)
