I even remember some of my friends' cell phone numbers and I don't have anyone in my phone's phonebook, if I don't remember someone's number, I'd probably have to look it up in my emails or chat logs.
That's probably pretty uncommon even for Fedi and probably stems from the times when I didn't own a cellphone at all, not too long ago, now that I think about it — I've always hated these things and I still don't rely on them a lot.
