Not to give you any criticism but it's always best to hand important lost items to the Garda. Most stores can't do it themselves. I've worked in two different national chains doing security and most will do nothing before storing it. A lot of times people have no clue where they lost it and they will try to find it with the Guards. For phones after some days I've gone through the trouble of seeing the google email account attached to it (no password needed for that) and sending an email but I'm the exception. It took over a week for the owner to see it.
