should non-devevlopers go ahead with the update on september the eighteenth or ignore the ota from apple? it seems like the gm isn't getting the best reviews on some devices. the gm ought to be the same if i understand that correctly as what the public receives next week. i have an iPhone 4S and an iPad mini 3G. i am able to find many threads on throttled features in the iPad 3 / iPad 4 but not many on the mini. would anyone shed some light on what i should think about when updating? specifically, is the blur still present in the iPad mini? how is the performance? i assume things are going alright with the iPhone 4S as i keep reading; relatively stable and functional. i think there should be a performance guide for iOS7 on different devices since it seems to be in various stages of functionality across the device spectrum. thanks!
