Instagram becomes the next major app to ship an iPhone 5-specific update, as Instagram 3.1 is available to download now. According to a blog post, Instagram 3.1 is not only updated to be compatible with the iPhone 5 and iOS 6, but also comes with improvements to accounts recovery and registration.

First, the the account recovery. Instagram now lets you use Facebook to reset your Instagram password – in the troublesome event of a lockout.

“If you had previously connected your Facebook account with your Instagram account, just tap “Reset using Facebook.” We’ll find the Instagram account connected to the Facebook account you’re logged into and let you reset your Instagram password. We hope this makes it easier for you to regain access to your account even if you’ve forgotten or mistyped the email address associated with it,” they say.

Of course, you can still reset your password via email as well.

The big part of this update though is obviously the iPhone 5 compatibility. Like many apps that have gotten a redesign to showcase the new phone, everything on the app is now tailored to the bigger 16:9 display. Although this kind of compatibility is useful in apps like Twitter or Facebook, it’s really welcomed in entirely media-heavy apps like Instagram and Netflix, which just received its own iPhone 5-related upgrade yesterday.
