You do remember correctly. Number One was played by Majel Barrett, who went on to play Christine Chapel (remember her?)
My cellphone is a prehistoric flip phone that looks very much like a Star Trek communicator. However, anyone who wants to look at it and/or play with it will be told no (sternly or politely, depending on the situation). Plus, I didn't activate any games or any of the extras, as I only wanted a phone that could make and receive calls. I can text with it, but texting with this phone is a lengthy procedure saved for dire emergencies, and I've only sent one text since I've had the phone and it took me the better part of a half hour to send two sentences.
