Downloaded and experimenting with the new Bing that looks like it was added to Marketplace yesterday. It's BEAUTIFUL! What a difference. It would make a good one to review in the new section here for Marketplace app reviews I think.
I just downloaded over the old. The earlier version I had never rendered right (on my Verizon Imagio). This one is making all of the difference for me.
If you installed through marketplace and use marketplace to update it will prompt you that if you want to install the newer it will uninstall the older version. At least thats how it worked for me.
