I am currently in Zurich, Switzerland and find that my 270 does not work here. I can receive calls but not call out, and cannot retrieve e-mail or internet. Last year I was in Geneva with a 180 and all these functions worked properly. My service is through Cingular, which has roaming agreements with almost every carrier in Europe, but apparently not this one - identified as "diAx Swiss" on my 270. Anyone have any ideas how to get this thing working again? I am getting a very good signal, although not the GPRS signal.
