Right, I've decided I'm going for the £26p/m chitter chatter deal.
With regards to keeping my number and getting the PAC code from O2, should I order from chitter chatter first then get my PAC or does it really not matter which way around I get it?
Get your pac code from o2 it lasts for 30 days so when you get your s4 register the pac code with chitter chatter and supposedly within a day it will be changed over.
