EDIT: There is a fix for this bug in sdk 1.3.0-beta.2 available here: https://testflightapp.com/sdk/download/

We have a fix that is going to be ready very soon. It will be included in the next beta (probably 1.3.0-beta.2). I'm very sorry for the trouble!

More information on the crash for those interested:

There is an iOS bug that causes instances of the CTTelephonyNetworkInfo class to sometimes get notifications after they have been deallocated. Instead of instantiating, using, and releasing instances you must instead retain and never release them to work around the bug.
