A six-minute video posted on the iPhone Unlocking blog shows John McLaughlin, founder of Uniquephones, using a software unlock to allow his iPhone to function on the Vodafone wireless network to make two phone calls using the handset.

The video, which was shot using a Nokia N95 cell phone, demonstrates McLaughlin hooking the iPhone to a Windows PC, running a software program, resetting the iPhone twice as part of the process, then hooking it to a Mac, synching it to iTunes, swapping in a Vodafone SIM card and placing two calls.

According to Macworld News, Uniquephones already unlocks phones from several manufacturers, including Nokia and Motorola and cites about 60% of its customers as being in the United States.

A picture's worth a thousand words, so here's the YouTube video of the demonstration in action:

McLaughlin had reportedly planned to post his company's iPhone unlocking method on the iphoneunlocking.com web site last Saturday, but stated that he feared legal action from AT&T Wireless if he posted the software. McLaughlin, having received a phone call at 3:00 AM in Belfast from a representative of O'Melveny & Myers, a law firm acting on AT&T's behalf, stated that the caller said his company would be distributing and infringing upon the copyright of Apple's intellectual property should he begin selling the software to iPhone subscribers.

As of Tuesday, McLaughlin has stated that he's still undecided as to whether he'll distribute the software, but claims that the video shows the the process is possible.
