Arjun is correct, except Magnus stated he is using a Swedish provider, so the internet2.voicestream.com and wap.voicestream.com APs will not work, nor will the proxy address. First, make sure your provider allows not only GPRS ON the phone, but make sure they support your phone to be used as a GPRS MODEM. If that is the case, then they will need to provide to you the correct access point, and possibly a user name and/or password. You may want to have them look at the Advanceed settings, just to see if they apply to their network. However, paying the provider to browse the web on the phone is one thing, but being able to use your phone as a GPRS modem is something else. Older TMobile accounts do not have to pay the 19.95/month fee for modem use, like myself
