I'm looking into buying an iPhone 4s. I don't want a contract (don't send that many texts/use mainly wifi/etc), and you can find these products far cheaper on eBay than in phone shops.
However, i'm unsure as to which is the best buy: one that is already assigned to a network, or one that is 'unlocked'?
Does anyone know the pros and cons to either of them?
Also, what happens if i buy an unlocked iPhone? Where do i buy a sim card from? How much do sim cards cost? Once i buy once, do i just insert it, or do i have to register with the netwrok? How easy/difficult a process is it?
Any advice or information would be much appreciated.
Thank you.
