As AJ said, you CAN store more than one number per name. It's not that hard, but the default settings (store to SIM) won't allow it and the way you have to enter them is counterintuitive. The phone book system is not as good as others I've used.
I do like my V300, though. The biggest pros IMO are that it has a very nice screen, mp3 ringtones, Java games, and decent battery life. Cons are mediocre reception performance, slow processor (scrolling through certain menus sometimes takes a long time), and both the ringer and earpiece volume could be louder.
Also, my phone does lock up occasionally and we had to get my fiancee's replaced because it died completely.
Overall, I think it's a good phone with a good feature set, especially considering the price.
