hey, i live in canada, but have an at&t unlocked i617. i had wm6.0, and was able to get on the net using some settings, but once i upgraded to 6.1 they no longer worked. the above two settings did not work for me.. after some tinkering, these worked, give them a shot anyone with an i617 on rogers in canada (note, internet didnt, work, but secure wap did):

Description: RogersInternet
Connects to: Secure WAP Network
Access point: internet.com
User name: wapuser1
Password: wap
Authentication Type: None
Primary DNS:
Secondary DNS:
IP address: 172.25.0.107

Now in IE, go to Tools -> Options -> Connections:
Automatically detects settings: UNCHECK
Select Network: Secure WAP Network


These worked for me for internet!! Not sure about MMS or anything else that's all ive done so far.
Cheers
