5. Synchronizing, exporting/importing bookmarks
Due to the lack of direct file system access under iOS, it's much harder for iOS users to back up their mobile favorites to their desktops so that they can survive when they set up a brand new iPhone / iPad, without restoring a previous backup. (Incidentally, this is what I, in most cases, do – I try to stay clear from restoring over firmware updates so that restoring doesn't mess up anything.) It's only the, otherwise, inferior Safari that is supported by the online MobileMe and the offline iTunes bookmark synchronization; other Web browsers are not supported. As a third-party browser can't just access the favorites of the built-in Safari (the file containing them is in a private folder), for example iCab just can't import them. Unlike, say, Opera Mobile on Windows Mobile accessing IEM's bookmarks.
Very few Web browsers allow for exporting/importing bookmarks, which, in addition, can also be used for importing your bookmarks into another application. iCab, fortunately, does. The way this is done is explained in my original iPhone Web browser roundup in the section starting with “There’s another very nice feature I’ve already mentioned in the chart, but it needs to”.
In the meantime, iCab has also received DropBox support, which allows for remote backup and restore of bookmark files. Note that it, unlike with desktop-based saving, doesn't allow for saving and restoring your bookmark files using an arbitrary name – the file will always be /iCab Mobile/Bookmarks.html. That is, you can't keep separate versions of this file in your DropBox account.
Using DropBox for backing up and restoring your bookmarks is very easy. Go to Settings > Dropbox, link to your dropbox if it isn't already linked by tapping the uppermost “Link Dropbox” and entering your e-mail / password pair (you can even create a new account right from there) and, then, tapping Export Bookmarks to DropBox. Importing in the opposite direction is equally easy.
Note that the only other app, Aarde, to currently support DropBox, only offers image upload to there, not bookmark synchronization.
I've, answering a question HERE, checked out the bookmark export/import capabilities of Atomic. Exporting is much simpler than in iCab: all you can do is mailing the bookmark file to yourself (Settings > Import/Export Bookmarks > Export Bookmarks). The HTML file this uses can directly be clicked to access the favorites in a Web browser – or imported into, for example, iCab Mobile (I've tested this).
Note that you can't directly upload to DropBox from inside Atomic and you can't just send the HTML file to iCab Mobile (or, for that matter, any iPhone Web browser) from inside Mail by using “Open In”, should you try to open the bookmark file you've mailed yourself.
