How can I find out what network my iPhone is locked to?
I purchased an iPhone off of eBay to replace the screen, but the seller did not know the network lock and I am stuck at the activation screen of iPhone. I know that to get past this activation I need to insert a SIM card from the respective network. But I don't know what network the iPhone is locked to, so I don't know what SIM card to get.
How can I find out what network my iPhone is locked to, bearing in mind I can't do the usual trick of, "Settings > General > About".
