iOS 7 was just released for developers in the form of Beta version , so the normal people couldn't get the taste of this fairly newly designed OS but Cydia Developer has released a Winterboard theme that changes the icons of your springboard to iOS 7 ones , it's pretty good but you don't get the full iOS 7 experience only the icons changes , But it looks pretty good for a winterboard theme, but if you want the iOS 7 lockscreen you can download iOS 7 lockscreen form the Bigboss repo , iOS 7 theme is available for no cost on ZodTTD & MacCiti repo.
