From iTouch to iPhone with a Download

From iTouch to iPhone with a Download:
“Competition to turn an Apple iPod Touch into an iPhone is heating up among application developers, with VOIP provider Jajah joining Truphone in blurring the difference between the wildly popular devices. Unlike the iPhone, turning the iTouch into a telephone doesn’t require a two-year contract or an expensive data plan, only a Wi-Fi connection.”

Now this is what I want. I’ve heard that you can force a phone company to sell you an iphone without the data charges, but I’ve not no interest in fighting with people. Why not a technical workaround rather than a confrontation?
