I have a work Nokia 6310i and am looking to get my 'own' phone, possibly a K750i, for as cheap as possible. SIM-free makes sense in a way, as I don't need a contract (will use the work SIM), but if there was a really juicy offer, then the missus could use the 'new contract SIM' in her phone (currently PAYG). Looking at various websites, I'm a bit bamboozled, and not sure of which would be the best way to go... So, SIM-Free, or contract? And where's a good place to look?
