Silicon.com has posted a roundup of true stories about how mobile phones saved the day. Some are quite humorous:
"I was researching my family tree by browsing through the burial records which are held at the local crematorium. I was placed in a small room and was so engrossed in my research I didn't realise the time and it appears the staff forgot about me, locked up and went home. With my trusty mobile, which I'd only had for a few weeks, I phoned the local police station who arranged for the key owner to come and rescue me."
