AT&T Smartphone Mobile Phone GPRS settings

After acquiring a couple of GSM smartphones, I discovered that there's a lot of mis-information about how to properly configure these devices for internet access. This is especially troublesome for phones that has been unlocked, and is being used on a different network.

I've compile enough information to get my unlocked "T-Mobile" HTC Dash / S620 / Excalibur to work properly on the AT&T network.

The setting are as follows:
(WM 6.1)
1. Start / Settings / Connections
2. Goto "GPRS"
3. "New..."

• Description: AT&T GPRS
  
• Connects to: "The Internet"
• Access point: wap.cingular
• Authentication type: "CHAP"
• Done

That is enough to get Internet Explorer and Email to work. From my Blackjack II (SGH-I617), there also is a setting for Proxy, which didn't seem like it was necessary. However, here's the info.

1. Start / Settings / Connections
2. Goto "Proxy"
3. "New..."

• Description: AT&T WAP
• Connects from: "The Internet"
• Connects to: "WAP Network"
• Proxy: wireless.cingular.com:80
• Type: "HTTP"

I hope this works for you.
