May I ask why he will need big numbers? I am at the age that I need some big numbers in order to see them without my glasses, but I am using the Blackberry 8820 without any problem and I love it. The numbers automatically light up when the backlighting on the keys changes which is a plus for me. I was worried about using it because the keys seemed small and my fingers are rather large. I have no problem with seeing and hitting the keys with my glasses on and it allows me to have everything that I wish to have in a phone at a really great price. If his reason for needing big keys is because of the reasons that I have previously mentioned, the 8820 was a great choice for me.
