My AT&T GoPhone needs to be replaced. Thinking of purchasing a used phone from a friend...Sony Ericcson W518a. It was a contract phone he purchased from AT&T but didn't like so he replaced it. My question...will my AT&T GoPhone Plan work in the Sony? Can't find anyone who knows for sure and I don't want to make the purchase until I find out. I don't really know what "unlocked" means *duh* Please help!
