Have had Palm and Palm Desktop for years with large address book and liked being able to update on the desktop or PDA and then just sync. Whole new world with BB. I thought the BB Desktop Manager would work the same way but it only backs up, you can't enter any data manually in it like Palm Desktop. My surprise. Just got BB Curve 8530 to replace both my old cell phone and PDA. You are correct Blackberry Desktop does not let you transfer from the T/X directly only other Palm smartphones. The entire process was somewhat painful but worth it. First, I exported my address book in Palm Desktop to a comma separated value (.csv) file. Then I imported it into Outlook 2007 after creating another Contact List because I previously used Outlook for a totally different set of contacts and didn't want to lose them. By making a new contact list I could keep them separate. The trick is to be very careful when you are mapping the fields. In some cases there is no equivalent. Also, it depends how strict you were in using the correct fields with your Palm. Once you have completed the mapping you can sync your BB with Outlook through the BB Desktop Manager. Again make sure you configure the settings exactly how you want them in the BB Desktop Manager. I chose to have one-way sync at first, Outlook to BB, to test (as I did have some contacts that I had manually added to BB) that I didn't want back in my Outlook Contact List. Once you know you have it right and have all the information in the right fields, you can switch the sync to both ways. The good thing is if you don't get it right you can just dump the Outlook contact list and create a new one with the imported .csv file and remap what may have been incorrect. For instance, depending on how you set up your Outlook to read (first name, last name) or (last name, first name) it may not produce the desired results on your BB. Also, I had a lot of information in the notes that didn't all come in. So when I was done I went through my almost 400 contacts one at a time to verify if there was any missing information and corrected the Outlook contacts or format so it would sync with the desired results. It is working beautifully now, no problems. The pain has been forgotten! Good luck. I will be looking to see if someone has come up with a better, faster, way to do this (too late for me) but would be interested to know.
