SmartPhone 2011

So, did some calculations on the options for upgrading my phone later this year (18 month contract started Christmas 2009 so will expire in a few months).

As of February, the cost for a iPhone 4 on O2 comes with these payment flavours:

Contract  Months Purchase Average_per_year

32Gb iPhone4 £25.53 24 £350 £39.58

16Gb iPhone4 £25.53 24 £305 £37.71

32Gb iPhone4 £30.64 18 £336 £49.32

16Gb iPhone4 £30.64 18 £223 £43.58

Seems we'll get a bit of cash back for my 3GS phone using http://www.mazumamobile.com or I'll give it to Lucy?
