Keep the updates coming...

Great SIP app - very straightforward setup and use.
I notice a few changes in 2.2 that might have been better left alone - like the ability to disable Cellular access. Very handy to ensure you dont accidentally make the call over the wrong network.
Also, I am almost CERTAIN I made VoIP calls over 3G with version 2.1 - even though it wasnt supposed to be supported. Lets get that feature back!
Also - Bluetooth headset support is an absolute must.
Keep up the good work.
