Hi,
I've just run that branch and tested with : * iPhone 2G * HTC Magic * Cheap nokia 1661
And I didn't notice any weird behaviors. Each was able to register and place call/send sms without trouble ...
Feel free to start testing the system_information branch if you're interested. I'd be happy to hear any "master works for my phone, but system_information branch confuses my phone" kind of reports.
Nope sorry, it works fine here ...
