What is the best way to make the fonts larger on the N80?.....I've seen software on this website posted, but I'm not sure if it will work with my phone.
I tried different themes. but I need larger fonts......

I've attached an old topic that briefly talks about the same issue - http://www.allaboutsymbian.com/forum/showthread.php?t=46234&highlight=font+n80

;)

As a compromise you could change the application screen view to list instead of grid. (Options > Change View > List).
