Now its not new in this blog...facing since last tuesday mid-night after I updated to ios 6.1.
Is there any true solution...I almost tried all available possibilities...holding the home button for a while,sign out sign in,changing date/language,together holding home button and sleep button untill silver apple appear,network set-up,wi-fi to 3g.....NOTHING WORKING...and I have a strong believe that its a app store problem because so many people facing it...
