Raw software

I was almost Happy when found this program allowing incoming calls through Google Voice service on my Ipad. Works fine while you working inside iGVoice, but when you minimize it or turn your screen Off, incoming calls stop to work. Hopefully this BUG will be fixed in future versions, but now I feel cheated by iGVoice developers and iGVoice useless because can be used properly only as many other FREE dialers and couldnt provide something mor money paid.
IGVoice support has slow reaction, no reply, or just very very busy...
