What GSM providers are you guys using when taking ED? Cingular is way too much, I always buy prepaid sims but if I'm going to be in 3 different countries thats a waste..riiing looks pretty good, free incoming all over europe with a lichenstien number, and .39 euro cents to call europe or usa..lichenstein number is also good because calling from usa to there is a lot cheaper than the rest of europe...must be their taxes?

Anybody used riiing?
