FarEasTone internet GPRS/3G mobile phone settings?

I just bought a Sony Ericsson G700 and I have post-paid Fareastone simcard (3G capable) with a Cross-Net 365 plan.
When I first started the phone, it automatically set up 3 different types of internet accounts. I am a bit confused about which account to use for internet access or email and what’s the difference between these 3 accounts?
I have tried to connect to internet and the 3 of them had no problem, but some websites were not accessible with one of the connection. Here below are the accounts details, and if anybody has any idea about what’s the difference between them, or even if GPRS/3G access/rates are involved, I would be happy to understand.
