Plugged your iDevice into an iTunes-equipped machine lately? You should. Apple has just let loose iOS 5.1.1, a seemingly minor point update that actually promises to fix quite a few (potentially) substantial quirks. Coming two months to the day after the iOS 5.1 software update, the extra 0.0.1 is said to improve reliability of the HDR option for photos taken using the Lock Screen shortcut, address bugs that could prevent the new iPad from switching between 2G and 3G networks and solve a few issues that were affecting AirPlay video playback "in some circumstances." There's also improved reliability for syncing Safari bookmarks and Reading List, and Apple has purportedly fixed an issue where 'Unable to purchase' alert could be displayed after successful purchase. Sucked the update down yourself? Let us know how it goes in comments below, and peek the full changelog just after the break.
Update: Looks like iOS 5.1.1 has already been jailbroken. Huzzah!
