I recently installed the treo600 updater as requested on the palmone website. Now after the first hot sync, the phone shows a peculiar small arrow next to "verizon wireless" and crashes if I access the phone preferences page. It's not a 3rd party software problem because I don't have any on the phone. Verizon makes you wait forever for support and is clueless once you get there anyway. So someone out there will know or nobody does. Thanks.
