How to manually configure your iPhone 4 access point. *Solve connect to cellular data*
For some of us unfortunately you can't configure the access point straight from the "SETTINGS" menu in your iPhone 4. This is a website which will let you manually set and download it straight to your iPhone via WIFI connection 1. Connect your iPhone to the internet via WIFI. 2. Open Safari and visit help.benm.at 3. At the country selection page go to the bottom-most and select "Other or Custom" 4. Key-in your operator's name, access point, username & password. 5. Finally Download and Install the downloaded configuration. 6. Turn off your WIFI connection and try to use a cellular data connection to surf the web. That's all, hope this helped some of you. I've tested this on an iPhone 4 running version 4.3.3 Not sure whether it'll work on ios5...
