Best way to I.D. an old BB model?

[tabcourt]

Is there a site that has pictures of all the BB models? I'd like to try to determine my wife's BB's model number but only have its appearance to go by. I think it's a 87XX series.

From her main screen, open

Settings> Options > About...

You'll see her Blackberry model number there.

Also the model number is found under the battery.

if it is an 87xx series it will have a trackwheel on the right side, and it will have 3 keys across the middle above the keyboard, with a clear plastic over the lcd
