I bought iPhone 3GS for £120 from a friend. When putting the sim card into the iphone it didn't read it but still turned on etc. I took to a high-street shop and they unblocked it for me and now it reads the sim but doesn't allow me to make calls or text.

Does this mean its blocked/barred? If so, is it now unusable?
