CellID and signal strength

I am working on an application to record signal strength similar to
miniGPS and tinyGPS. Also see:

http://gsmloc.org/

I am curious about whether signal strength is something available to
developers on all phones or whether this is something that is not
exposed from the radio interface normally?

My second question is whether UK operators allow users to install native
applications on their phones or are they completely locked down/can only
install J2ME apps?

Curiously,

S.

Not sure if this is any good to you, but I use net monitor - it could
easily be enabled on DCT3 Nokias.

It may be capable of working on other phones - try searching this group
for 'net monitor' as a starting point.
