Interesting, this is the next horizon for Voip, the ability to use voip via your cellular phone. This is where wifi-enabled phones, which are just beginning to enter the u.s market, will come into favor. Skype has just released their Vox service, www.voxlib.com,
Voip Inc. is also in this arena, inpart from their acquisition of WQN (www.wqn.com) This is big and i'm in the process of testing both services to help lower my phone bill by eliminating roaming fees.
