hey, i've tried out the previous betas and i actually love iOS 7 but my regular use of apps such as snapchat, instagram or twitter started to crash in beta 1 and 2 and i was wondering if beta 3 is much more polished then ever to an extent that it is usuable with little frustration to crashes. i can handle an app crash just once but not if it constantly occurs when im trying to show someone something.. anyways thank you for your help currently using 6.1.3 and i was wondering if iOS 7 beta 3 is worth it to upgrade
