well it's not an iphone, cause if it was, and that person had mobile me, they could have easily found it, and if they were smart enough to put mobile me, on an ipod touch, for a back up plan, it would have been nice, but could have not worked efficiently as an iphone due to lack of GPS.
but since you tried very hard and found no owner, I guess you could go to an apple store, and unlock it, or place it in DFU mode, and restore it's settings in itunes,
like I heard other people do it.
but don't feel bad OP. if it was an iphone, i would have been mad as hell, but with an ipod touch, is like
finding a dollar on the ground you are not going to place it in the
lost and found most likely you will keep it,
but finding a lost iphone is like finding
a letter with an address and some money inside.
but if you find something, at least contact the people addresed in it's contacts..
