For those who don't know, truphone is a voice over ip application that can be downloaded unto the iphone and is customized to work with it. Now I havent bought an iphone yet (if I do it will undoubtedly be an unlocked one) and the main reason why I'm considering burying one is because of truphone. I'm about to go off to college in the states (I'm canadian) and would like a cheap way of staying in touch with my friends and family. (And international plans are freaking brutal). So my questions are: - How well has truphone worked for you? - Is it better on the 3G than on the old ones? ** Is it possible to ONLY use truphone without a plan? Can you establish it in a way as to have a receiving number and do all your incoming/outgoing telephone calls through it? I think I would still end up saving money. Thanks in advance!
