If you use Missing Sync, it's going to ask you to upgrade to 5.0.2 today. If you value your sanity (and the contents of your calendar and address book) I really recommend you not. <LJ-CUT text=" --More--(13%) ">

Here's what I sent via their feedback form last night. No reply yet, except an auto-reply saying that the company will be completely shut down for Thanksgiving! Making it even more awesome that they did a release the day before. "Time to ship, save your buffers!"

I upgraded to 5.0.2 and synced, and all kinds of bad things happened:

• every email address, postal address, and AIM handle in my addressbook was duplicated: if someone had 3 email addresses, now they had 6.

• the tags on lots of those addresses changed from "work" or "home" to "other".

• every "repeat yearly" entry in my iCal was duplicated. Now there are two copies of every birthday reminder I ever entered.

So I restored Library/Application Support from backup and tried again, this time saying "overwrite handheld at next sync" for contacts and events. That seemed to work at first, but:

• then the next time I synced without doing "overwrite", it screwed up the start times of all of my events! E.g., every event that was "8pm - 10pm" is now "12am - 10pm"!

Should I downgrade to 5.0.1, or do you expect 5.0.3 to be out almost immediately?
