I updated my Treo 270 without any error messages and everything seems working fine until I tried to make a gprs-connection to my provider (Swisscom).

Everytime I try to connect following error message appears (in German): "wrong GPRS Access Point configuration...".

The strange thing is: with another SIM of the same provider and without any changes in the network preferences it works!!!

In the meantime I got another SIM from my provider but as I supposed the problem isn't solved. My provider also checked all account params, everything should be fine..

Any idea?
