Worked flawlessly on my iphone 5 and I have cydia working as well. The biggest PITA was installing itunes on a windows 7 box. Must have taken 15 minutes to install with about 40 different status bars so you never knew the overall progress of the install. Windows is a joke of an os.
Or maybe CrApple purposefully made 15 status bars during the install. Because most installations for other programs don't do this. Seriously get a grip.
