Lost my Sony Ericsson Arc S December 22nd

I lost my phone on December 22nd 2012 on dame street in dublin city centre.I got a taxi from the Mercantile pub and i was also in Ricks Burgers take out beside the Mercantile.Im nearly sure i dropped it in the back of the taxi.My phone has a black leather case on it and is silver in colour at the back and still has the plastic on the screen of it.A generous reward is on offer if someone has it.
