The thief who stole my iPhone...

The thief who stole my iPhone could face time.

This is a pun. For someone to "face time" means that they are in jeopardy of going to jail, however facetime is a phone app that is available on iphones. If you stole an Iphone it is possible that you could go to jail for it, but it is also possible that you could use the app face time (if you unlocked the phone successfully)
