Tap in *3001#12345#* and enjoy :)

Any more hidden iPhone codes?

Oo, what does this get you? Is it similar to the old Field Test app one could run on a 6680, with details of what you're connected to and the signal strength etc?

Yes it is quite detailed - I'll try and grab a screenshot and post it up.
