VoIP SIP Client on iPhone App Store

A few days ago I discovered that there was an actual SIP client for the iPhone that was not tied to any specific provider and that had a keypad whenever it was in a call (FRING has some weird splash page, nothing useful). The application is called SipPhone and its from a company called VNET Corp.The main thing here is this is a completely legal VOIP/SIP application on the iPhone. There is no need to jailbreak the phone in order to use it. Because of this, it only works over WIFI and not over EDGE/3G.

The application is $6.99 but honestly, if you have a SIP account ( Gizmo5 provides you with this ) this should open so many doors for you the price should be negligible.

Get it before AT&T complains!
