That is the verison that Verizon is shipping on the CD with their Pearl 8130.

I had DM 4.2sp1 installed on my XP SP2 box and used it with my T-Mo Pearl and a few other device... Un-installed it months ago...

Installed this DM 4.3 when I got the Verizon Pearl... Install went ok.. it found my T-Mobile Curve and installed all drivers just fine, DM 4.3 sees it, asks for the Device's password, and goes...

BUT driver install of the Verizon Pearl would not complete with the new RIM Device Drivers... USB Mass Storage device feature's driver didn't install properly for the VZW Pearl (got error code 10)... Had to pull out the older RIM drivers..

While DM 4.3 works fine... Roxio Media Manager is Extremely SLOW starting up... it appears HUNG with a white screen, doesn't fill in, etc... then finally comes up... (Thinkpad T60 CoreSolo 1.66ghz, 2gig ram)
