For those of you interested, you can get a free US phone number for incoming calls through Aim Phoneline.
http://phoneline.aim.com . (AIM=AOL Instant Messenger). It seems a pretty good deal. Outgoing calls cost money, but incoming calls are free.....and it has free voicemail so if you aren't logged into your AIM(which for me is 100% of the time), you can just check your email...voicemail messages are sent to your email.
Only catch: you have to get a phone call once every 30 days to keep it active. If you dont have many people calling you, you can spend the cash to make a call to yourself once a month...a cheap price to pay for a US phone number.
