How To: Use your iPhone data plan with iPad

Here are the APN settings that are required:
APN name: wap.cingular
username: WAP@CINGULARGPRS.COM
password: CINGULAR1
After changing the APN settings and enabling cellular data I again used Safari to test out my internet connection. It stuttered at first and I thought I had failed, but soon the connection picked up and I was browsing the web over 3G. It was very exciting to use my iPad over 3G for the first time all without having to pay for an additional data plan.
