Definately go for the new one Stinky.
I'm personally going for 32GB, I'll never get near 64GB (and probably not near 32GB either but there we go) and it does cost a fair whack more.
yea i usually end up going.... well maybe ill need the bigger one maybe ill need 3g maybe ill need 64gb lol
but if O2 dont charge insain money for tethering then i wont need the 3g. i suppose if they do i could go for a three mifi and link it with that. prob be cheaper
