A company I’m calling iCraw just announced a VoIP system for the iPhone that allows you to hop onto a VoIP network mid-call whenever you hit an open hotspot. It also offers free calls to the U.S. and Canada. It should be available on the Apple iPhone App store next week. Since I really enjoy T-Mobile’s Hotspot@Home UMA offerings, this sounds like a great way to save some money and get even better call quality on a non-T-Mobile phone. Here’s the feature list:

* Make and receive calls over WiFi
* Transfer inbound calls from your regular cell minutes to WiFi instantly
* Access your same address book
* Customize your voicemail options

Why is it now iCraw? Maybe if the founders could figure out mail-merge in their email application…
