When was the the first handheld phone invented?

we did ours at the actual reptceion cuz we did the bubbles when we left there. I actually had a bubble boy (little bro of one of my Jr bridesmiads who was very disapointed he wasnt the ring bearer, but hes a little hellion and I didn't trust him on stage .so i gave him that job!) We let everyone get their food and then I got him to walk around with a bucket full and pass them out .he felt all important! If you are doing it as you leave the ceremony I would give them out with your programs so they have them more together so you can make a quicker exit.
