Iphone taken from mace killinarden tallaght

I left my phone down while i was in the post office and it was taken by someone, it means alot to me even with the damage(cracked screen and broken home button) added up to 120euro its more a personal thing with alot of my make up photos on me, and there was also photos of my 11 week old pup that me and my bf nursed from 3 and a half week until she suddenly died two weeks back. =[ im offering a reward and just need it back. Its locked and has a phone number on the front of the screen, call it if you have it please. Its an iphone 4s in a clear case and has a steal purple back on it.
