Hi there: Thanks for suggesting Fring. I downloaded it to my phone, registered it, no problem. Then what? Tried calling the UK, no luck, said I'm not authorized to make long distance calls, so I watched the videos on youtube and joined Iptel.org - signed up with them to get a SIP account (although I've no idea what that is or how to use it), and then went back to Fring, chose SIP in my "add on", and logged in although I have NO idea what my SIP proxy server address is (I skipped that entry) - then tried dialing the UK - just got a strange beep and that's it. So now I'm stuck. Like most of these things, I"m sure it's a steep learning curve and then it's easy, but to me this is really brand new stuff and I'm flummoxed. I'm going to be in the UK for two months helping out with my sick mum, and I need to be able to call the US from my htc hero from over there, using wifi. So if anyone can give me any EASY TO FOLLOW directions (talk to me like I'm 4), I'd so appreciate it. Thank you!
