I've been given the choice of getting a new K750i by either upgrading my
Vodafone contract and paying £100 or porting over to CPW's SP and getting it
for free. I assume my bills will be affected (at least cosmetically), which
may be a problem since the contract to be upgraded is one of multiple phones
on a single business account.

... So benefits and drawbacks? Are CPW support better than Vodafone's? Is
there any difference in billing (apart from physically)? Would I have to set
up my DD again? If so will the money go in a sepearate transaction to the
other phones left with the Voda SP? Or is the whole thing transparent?

Thanks!
