Anybody know the Iphone 2g Happy DTAC Gprs settings? I can't seem to get mine to work and the instructions given via the call center weren't that clear.

I don't know it works for your iphone 2G or not but let's try:

Visit this web and follow the instruction : vas.dtac.co.th/en/ota2008

or contact them by online chat call center at dtac.co.th/english again.

Hopy you can set it soon

Got it already. Actually I called the call center again and this time they just flipped on some sort of switch and I got the "E" sign up on top once I restarted my phone. Didn't have to touch any settings.
