How to force the iPhone to obtain a new IP-address


What is the fastest way to force my iPhone to obtain a new IP-address?

One way to get a new IP-address is to simply restart the iPhone, but that is rather slow. Is there any faster way to obtain a new IP-address?

I'm running iPhone OS 3.0 and I'm getting my Internet connectivity over GPRS.

The quickest way I have found to reset all the network connections (wifi, 3g/edge/gprs) is to go to settings and turn on "Airplane Mode" for a few seconds and then turn it off again. It will reset all network connections.

Settings-->Airplane Mode

I have found this also to help when my phone doesn't connect to 3g in a known 3g area.
