The 18 month contract I took out when I got my 3GS was up in December and wondering what my options are?
not too fussed about getting an iphone 4 as 3GS is fine (and will probably wait for iphone 5).
I would be interested in lowering my monthly bills though as they around £30 for 75 minutes and 125 texts (which is pretty crap).
I heard tescos do some good deals now, which is O2 anyway? I dont want to change my number though.
Any suggestions?
