Ok so I'm thinking of getting a sony ericsson phone with wifi - i think its called a smart phone right?
Anyways, i wondered if I could buy it unlocked and put my Vodafone sim into it. Will I still get all the features, and will the phone definitely take the sim card?
I don't want to fork out a load of money, only for the phone not to have all the features.

Gracias in advance.
