Lost Samsung Galaxy Phone, (white cover case) Lots of Photos stored - Reward offered

I lost my phone on Friday June 14th, after the Robbie Williams concert. It is a black Samsung Galaxy S3 in an off white coloured case. We were in the Ballsbridge area and picked up a cab outside the old D4/Jury's Hotel in Ballsbridge. If found please please please contact me.I have a lot of family/sentimental photos stored on it which cannot be replaced and were, sadly, not backed up. I will reward generously.
