Ok here's my final question (I hope). I already have a bunch of really great bookmarks on my phone. Now if I go into IE and add the bookmarklets and then try and sync them over to the iPhone, I'm guessing that it will erase all my iPhone bookmarks in an attempt to match them with my IE bookmarks. How can I avoid this? I wish there was a way I could have it merge my iPhone bookmarks and my IE bookmarks together on both my computer and my phone.
I don't know for sure, as I started syncing bookmarks early on, but I would hope the iPhone's bookmarks would be added to IE's and not erased.
I know that any bookmarks I add on my iPhone are added to IE on the next sync (and vice versa, obviously). But I am not 100% certain that, during the first bookmarks sync, the PC doesn't overwrite everything on the iPhone (though I doubt it).
I like having the ability to sync and manage bookmarks via my PC. I use the FF extension "IE View" when I run across a link that I want to bookmark on my iPhone: I right click and choose Open in IE, and then in IE I bookmark it. I also have created my bookmark folder hiearchy on my PC, and it propagates nicely to my iPhone (and vice versa, should I make folder changes on the iPhone itself).
