I was in Phones 4 U today and they offered me an N70 for £49.99 on a £25 per month contract. I'd change that after six months to the £15 a month one though, so it all works out at.

(Phone) £49.99 + (first six months £25*6) £150 + (second six months £15*6) £90
= £289.99

That was in a shop so I assume that someone on the net does it cheaper?
