It hasn't been asked in a number of years, but is it possible to request a number or choose one from a list.

If so, which telcos can give this option

The company I work for is now mandating their own very locked down handset, and I want to keep my existing phone so can use the existing personal apps/configuration (plus it's a much nicer model)

I only need to get a basic plan/pre-pay, as my existing data usage is relatively low (most months under 1GB .. summer is under 2GB) and majority of calls are work related.

The company uses VF, but I have no personal preference ... the rest of the family uses 2degrees and VF on pre-pay.
