I'm thinking of purchasing a tmobile unlocked 8320, will i be able to put skype on it as I am almost always in a wifi zone?

thats the question i have to?
cause i just bought a bb bold today and i cant use the wifi to go on the internet
i tried those codes in th tcp and they didnt work for me?
i'm also with rogers

so if i had this phone unlock would it enable me to use wifi alittle more freely?
Thanks!
