We have received few emails from customers stating that they have issues with their Internet on the iPhone after jailbreaking.

The issues focus on no Internet connectivity (no 3G network or EDGE network connection) as well as Wi-Fi connection problems.

Step 1: On your iPhone 3G and 3GS, navigate to
Settings –> General –> Reset –> Reset Network Settings

Step 2: A dialog will prompt you with “Reset Network Settings” button as shown in the screenshot below.
