Here we go - Classic Blackberry Alert and Ring tones as MP3s (including Blackberry 3)
So, here they are all the classic alert and ring tones from the older Blackberries, including the classic "Blackberry 3" e-mail alert.
I couldn't find these anywhere on the net, so I made these myself by cracking open a 7250 and connecting a speaker wire directly to the surface mount buzzer on the main PCB and running it directly into the microphone jack on my PC.
