Fullscreen Signal Display

[Guest Shaunfarris]

Im trying to see if T Mobile can give me a decent signal over my existing Orange contract.

I have bought a T Mobile PAYG sim card to test but want some way of displaying the signal strength fullscreen on my device.

I only need it for a week or so, just to monitor the strength as I drive around, but the small icon on the tasbar at the moment is so small it wouldnt be safe trying to watch it.

So anyone, any ideas or can someone out there knock up a small app to do this
