An unsolvable what?

Geo-tagging works with no internet just fine. It takes longer to lock (design limitation of GPS system), and, if it didn't finish locking precisely, it tags the pictures with its best guess, for example GSM cell data. Or, if that fails, tags country by provider country code. I've had pictures tagged as the capital of whatever country I was in because I killed the camera app too soon.

Why would anyone need to "hack" that? It's working as well as it possibly can.
