Unlimited Calling on TP2 via VOIP?

[zillanilla]

Magic Jack is going to offer a device similar to Sprint's Airave that will allow unlimited calling on phones using GSM networks (source: http://tech.yahoo.com/news/ap/us_tec...show_magicjack). My questions are: 1) Would this be possible on a Sprint TP2? 2) If so, would the unlock be required? 3) Is anyone aware of a current solution for unlimited voip calls on the TP2?

The game is about to get interesting. I wish MagicJack had a stock symbol, I'd throw a couple chips their way.
