My friend has a blackberry, and says that I can call free long distance through Wifi but tweaking something in my settings. On my friend's phone, AUM or something will appear in the right hand corner of the screen, letting him know that he can call long distance for free through Wifi. However, we can't figure out how to do this on my phone. Suggestions?

Its called UMA and it has to be supported by your carrier. In the US, I know this is supported by T-Mobile. See here for more details.
