...as long as my phone book will be copied I will be happy.
So as I understand, and please forgive me but I'm just a user, for each type of BB we're using different Desktop Software, right?
There are several versions of Desktop Manager available, however v4.2 is the newest and will work with any BB, you just won't be able to use the Media Manager function. The great benefit of 4.2 is the Switch Device Wizard which makes swapping out BB's very easy. Good luck.
