Cross-posted from the Mac forum, in case anyone has any general syncing insights. Thanks!

So I'm having a few issues with syncing, and I suspect it may have something to do with the fact that I sync with two computers, two Macs to be precise. My issues are as follows:

- on a regular basis, my memos are I think quadrupled, or maybe even copied 6-7 times each, it goes from about 10-12 to like 60-70

- also on a regular basis, certain, but not all of my contacts' emails are categorized as "other," this is most annoying because they then show up in the contacts list as blank space

- what I've just noticed recently is that my personalized ring tones and pictures had disappeared. this may have been the case when I upgraded from the 650 to the 755 and I just noticed, but I'm not 100% sure. but what did happen for sure is that after I manually reset them, just syncing one time with one computer again erased the ring tones. why would this be?

Any insight anyone has into any of these issues would be greatly appreciated. It's pretty frustrating to have to deal with these things all the time. Thanks much in advance.
