iSync 1.5 is the worst thing Apple's released in 5 years. 1.1 worked well, 1.2 introduced some quirks, and 1.5 is a disaster.
Here are the worst bugs:
- Half the time, iSync doesn't close it's open bluetooth connection to the 3650, you have to shut down and restart your phone.
- Addresses are often duplicated. It's not clear why, but it happens every sync. Raking through my address book is like hitting the hitting plastic alligators with a mallet.
- Companys that aren't marked with the (new) "this is a company" are automatically merged with the alphabetically adjacent contact with a name. If a few cards like this are adjacent (or are duplicated, you end up with three mangled address cards.
- Twice now my iSync "internal database" has been corrupted, which means you have to rollback to your last backup and reconstruct your new contacts.
- Sync, and then sync again right away, you'll find there is often one more modification to make. I can not identify what it is.
- The 3650 and iCal treat repeating dates differently, so there are "conflicts" to resolve at every sync.
- Syncing a 3650 with multiple computers (same .Mac account) causes all appointments synced to the phone to duplicate. There is no way to roll this back.
- Calendars that are hosted on .Mac are often duplicated (with the same name!) totally arbitrarily.
- It's very difficult to delete contacts, and often deleted contacts come back double!
- A few of my contacts had the mysterious note "0" in their address book entry. These contacts didn't sync.
What's especially frustrating about some of these bugs is that they're inconsistent, which makes me think something is very wrong with the basic program. For now, I continue to use iSync because i remember when it worked near perfectly, and also because it acts as a Zen exercise during my day. For now, I've turned off syncing calendars.
There is a new "relationship" field which offers some promise, and perhaps a hint of the Address Book / Buddy List to service conversion that Tim O'Reilly suggests. I'm hoping that these hiccups are obstacles long the road to a more ambitious technology.
