the window for jailbreaking on iOS 7 is closing rapidly, with the upcoming release of iOS 7.1 in the next few weeks. If you want to jailbreak on iOS 7, you'll have to update before iOS 7.1 is released as iOS 7.1 plugs several jailbreak exploits and is currently not jailbreakable.So I still am on iOs 6.1 JB with my iPad 2 and wondering what folks who have upgraded to 7 think of the performance. I have held off due to performance concerns, but am thinking about updating. Thoughts?
