I switched from a Treo to the Blackjack 4 weeks ago and I sorely miss
the fact that I could figure out who called me without having to put
my reading glasses on. Does anybody know how to change the font size
for displaying the caller?

Trying to be smart I decided to associate jpeg images with the
"popular" callers, but unlike the Treo where the image takes the whole
screen, the blackjack just displays a minimal thumbnail of the jpeg,
which without my reading glasses is totally useless. Anybody know how
to change the size of the image?

Finally, when in the office I have the phone on vibrate mode. With the
Treo it would have two short vibrations if it was an email and a set
of longer vibrations if it was a phone call. With the blackjack it's
all the same, long vibration (one for an email message, a set for a
phone call). Since in carry the phone in my pocket, I literally have
to wait for the second long vibration to know if it's a phone call and
then hope I have my reading glasses to see who is calling me. Anybody
knows how to program different vibration modes?

Thanx in advance!
