Change APN setting in iPhone OS 3.0 beta
In iPhone OS 3.0 beta, the Settings->General->Nework->Cellular Data Network is empty, so we cannot change any APN settings. So if you have to manually change APN setting, you cannot use any 2G/3G network.

The website will create a profile, confirm to install the profile to your iPhone
