I purchased an iphone 4 through craigslist, probably not a good idea I know, but I had no upgrade available. Anyway, so I bought it, when it came to me, it was semi-activated, meaning there was a phone number listed but no service. I took it to a sprint store and they told me its been previously activated and they can't activate it under my plan. So my question is, what are my options? I know you can unlock ATT phones, but can you unactivate sprint iphones? Thanks in advance.
edit: and if it's against the rules to discuss the jailbreaking aspect of it, then scratch that, and just answer if its generally possible to activate it or is it locked forever? Thanks
