BB Storm :: Saving New Numbers From SMS

I think I'm going a bit crackers, I have a Blackberry Storm 9500 on Vodafone PAYG, and cannot for the life of me work out how to save a contact from a new SMS. I tend to give out my number, people text it so I have theirs, but saving them as a contact from the initial text is proving impossible.

I have tried C&P, doesn't work on anything other than the text fields within the messages themselves, so if they don't type their numbers in the actual text, I can't save them. There is no option to save them in the Blackberry button menu, just to call or SMS them. There is nothing at the top of the conversation that is "clickable", there is just the little person icon and the number, clicking either does nothing, it doesn't select. Same with the number at the beginning of each subsequent text from them - doesn't select, can't use the highlight/copy function on them.

I know there is the long way round, to write the number down then input them but this seems like such a basic function there must be a way to do it directly? If not I think this along with the other function issues (short battery life, regular freezing, low grade MP3 player functions) are going to make me swap it for something else. Shame as I still think the click touch screen phone is ideal for me personally.
