Hi, I got a jailbroken iPad2, with iOS 5.0.1. installed. I use XBMC a lot and I wanted to use it as an awesome portable media player, so I just got myself an HDMI digital adapter from apple store. When I tried it, I just get a pop-up that states "This accessory requires iOS upgrade". After talking to the Apple support, I found out that the newer HDMI cables requires iOS5.1 to work, so I'm stuck. After searching the web, I found a way of fooling applications to think 5.1 is installed by altering the SystemVersion.plist file on the iPad. I changed it according to the instructions, but I still get the same error message when I connect the HDMI cable. Is there a way of fooling the cable that I have 5.1 installed, or do I have to wait for a jailbreak for 5.1 before I can use it?
