Well, the speculation is that it will be the next Apple iPhone, as reported on Gizmodo and they wouldn't give it back until Apple confirmed it was theirs!
There are quite a few web pages dedicated to the finding of this probable iPhone 4G in a bar. Someone sells it to a 'gadget news' website and then later, Apple wants it back (of course).
Seems that Steve Jobs (co-founder of Apple way back when) rings to ask for it back, and then there's an e-mail response because if they have not confirmed it belongs to Apple, what right to they have to request this device ?
