I am having trouble with my internet connection (HTC 6800 Alltel)

[MoonLightDrive]

I purchased my phone off of ebay as an unlocked 6800. It could be used with Alltel networks and Spring networks. I've talked to Alltel's technical support and i have the phone/txt working. However, my data plan (that i am paying for every month) isn't connecting to the internet.

I am thinking that it has something to do with going into the ROM/NAM/HDR etc settings and configuring what the values should be. Can someone tell me what the M. IP settings should be for my alltel 6800 htc so i can use the internet?
