With its latest update, Rebtel has added an iOS7 compatibility fix into the VoIP and messaging application. This should keep you chatting hopefully without issue when the new iPhone 5S/iPhone 6 decides to grace the world with its presence.
That’s not all the latest update brings, however. Rebtel also included a bug fix for a select group of users who were experiencing a crash whenever the application would attempt to start up. This bug was apparently related to the upgrading of old contact list data and would cause the application to fail to boot up properly.
This new and improved version can be downloaded directly via iTunes on iPhone, iPad, or iPod touch. Let us know in the comments if you happen to experience any further issues with the application.
