Does anyone know what are the usual 'other bug fixes' then mention in 6.1.3?
Counter jailbreak, counter more jailbreak and oh yeah another helping of countering jailbreak.
Looks like it's up for iOS 6.1.3 at http://support.apple.com/kb/HT5704.You can learn about all the things Apple has done in an update from this support page: http://support.apple.com/kb/HT1222
However, the URL for iOS 6.1.3 when I clicked on it just now, isn't working. Hopefully they fix/update the page soon.
