Weirdest thing I found so far on my 5.3.1 PW: When usbnetwork is on (had it set to auto, and on all the time over usb) active content gets really slow and unresponsive. The longer I use it the slower it gets. Particularly this one active content does that: Solitaire Collection (Kindle Edition)
. First thought, meh, badly programmed. But then I checked it out on my KT with 5.3.2 (non jailbroke still) and it was fine. Back to PW and disabled usbnetwork - now it doesn't have any more speed problems. So I deactivated the auto-switch, so that USBNetwork is off until I use it. Will check if it gets better with 5.3.3 and usbsetwork on.
Any explanation what would cause that?
