Upgraded from Acrobits Softphone

I`m really happy I did so. It works smoothly and without problem either on Wi-Fi and 3G network. I think this is the best SIP application for iPhone. There are many free ones which are good for someone who just start to use VoIP telephony, but I`m sure that sooner or later will purchase it. Keep good job Acrobits Team.
