So I randomly just found an iPhone on the street - still works but has a chunk missing off of the front top glass piece, just below the speaker. The broken part doesn't affect the actual screen at all. There's no info on it, looks like it was reset or something - I was gonna try and mail it back to whom ever lost it but I couldn't find any info. It also says there's no SIM card but it's an O2-service phone (assuming from Europe). I'm looking to sell it but have no idea on what would be reasonable, not even sure what version iPhone it is; think its an iPhone 3. Any constructive advice would be great!
