I don't want/need all my desktop bookmarks on my iPhone. I have a separate set of bookmarks just for the iPhone, organized for faster access, and loaded with stuff I have no use for at home. If you're like me (hopefully not), this tip might help. Unfortunately iTunes doesn't let you choose a specific bookmarks.plist to sync to the phone. It uses Safari's bookmarks, period. To get around this, up until now, syncing bookmarks with iTunes was a convoluted process of moving my desktop bookmarks out of ~Library/Safari to someplace safe, then moving a previously created copy of my iPhone specific bookmarks back into ~Library/Safari, then syncing, then moving the iPhone bookmarks out of ~Library/Safari and replacing the original desktop bookmarks back into the ~Library. Annoying and confusing. (I used color labels to differentiate the files) Today, I did my standard bookmarks Library dance, but for some reason iTunes decided to replace the bookmarks on my phone instead of sync. I lost several bookmarks I had made on the phone since the last time I did the dance. Grr. Frustrated with this, and tired of doing the swap, I figured I'd see what would happen if I synced my iPhone bookmarks to MobileMe. With my iPhone-specific bookmarks in place in the ~Library, I synced my desktop to MobileMe, checking "Bookmarks" in the sync options, and then checked bookmark sync to MobileMe on the iPhone. I got a popup on the phone saying all my bookmarks would be replaced with those on MobileMe. It worked as expected. All my iPhone specific bookmarks were back on the phone. Then I turned off MobileMe bookmark sync on my computer, and replaced my normal desktop bookmarks in the Library. I synced again with MobileMe, just to be sure I wasn't still syncing the desktop bookmarks. Then I went into the iPhone and turned off bookmark sync. I was left with no bookmarks as expected. I turned it back on, and voila, all my iPhone specific bookmarks were in place. To test it further, I created a new bookmark from a random page on the iPhone, waited a bit, then turned off syncing in Settings. All my bookmarks again disappeared. I toggled the sync back on, and my bookmarks reappeared, including the random bookmark I had just added. This means the phone and MobileMe sync bookmarks exclusively, leaving the desktop bookmarks out of the picture. No more ~Library/Safari bookmarks swapping. Happy guy. I'm sure no one cares.
