nooope but you can on an ancient Sidekick II Circa 2002
I just use my IGoogle page and create 1 Tab for Google Bookmarks and 1Tab for frequently used links.
Just change your homepage on your G1 to the IPhone version and your set.
IPhone IGoogle address is: http://www.google.com/ig/i
Now I can access all my Google Bookmarks, which are perfectly synced and categorized.
Plus my Links Tab is only the links that I use all of the time and each Box is its own category. (Weather, Social, News etc) Each Box only holds 6 Links but you can put as many Boxes as you want.

Box of Links Gadget found here: http://www.google.com/ig/directory?h.../mylinkbox.xml
This works perfect for me until something better comes along.
I added some screenshots of regular IGoogle Page and IPhone Version so you can see what I mean.
