IPhone 4S Lost last night

Hi

Just throwing this out there in case someone might be able to help out. I was out last night and I have lost my black iphone 4s either in MacDonalds Washington St or I'm nearly sure it fell out of my pocket in the taxi I got in. I haven't a clue what taxi company it was but I do know the name of the driver. I've done a google search and his name doesn't come up and I've rang around taxi companies and no one is of any help.

I've also contacted the gardai and to no luck.
