Apparently he recalled it well enough for Gizmodo to ID the Apple employee and make him (in)famous. So the finder or the Gizmodo people could have used another computer or smartphone to get in touch with him...it's not as if the prototype was the only internet-capable device in silicon Valley :)
Gizmodo:
"Weeks later, Gizmodo got it for $5,000 in cash. At the time, we didn't know if it was the real thing or not. It didn't even get past the Apple logo screen. Once we saw it inside and out, however, there was no doubt about it. It was the real thing, so we started to work on documenting it before returning it to Apple. We had the phone, but we didn't know the owner. Later, we learnt about this story, but we didn't know for sure it was Powell's phone until today, when we contacted him via his phone."

Wouldn't the owner of an Apple prototype most likely be...Apple?
Surely you're not asking me to buy the idea that they thought it was the engineers's personal property, and that if they sent it to Apple, it might never find its way back to him. That's an insult to even an average intelligence.
I'm just replying to the original upvoted post, "Didn't he/she know the engineer's name?".
Obviously the "finder" knew it was Apple hardware and the thug who stole my XBox knew it was Microsoft. The finder DID call the "owner" and most likely has it recorded. I'm not defending Gizmodo at all but I think the thief has a more compelling argument in court.
