Today, Apple released the third beta iOS 6.1 to developers.  In previous betas, Apple said that there have a number of changes from iOS 6.0.1 like how developers can integrate Apple’s new mapping service in their apps, some improvement for boarding passed being handled in Passbook and also few minor changes in Safari.  Let’s hope that Apple will release officially iOS 6.1 to customers in public release sometimes soon less than a month.
