I'm with Tmobile and am planning on buying an unlocked iPhone on craigslist or something. I was wondering if there was a special plan I needed for the phone to properly work just like Blackerry's or if i could just insert my sim card and that would be it.
Its just enough if you buy a unlocked iPhone. If you get a locked iPhone you need to unlock it, before inserting other network sim card. There are many ways to unlock a phone and I sort the safe way to unlock mine, through permanent unlock service from Simpleunlocking.com
