Yahoo! Go for the BlackBerry 8800 just became available yesterday. I installed it this morning via an over the air download. It is AMAZING. The user interface is fantastic, and it links seamlessly to my preset headlines/weather/stocks/flickr photos etc. on Yahoo! It also has a very easy to use maps and directions "widget" (that is what they call each of the various sub-programs) that kicks the pants off of the Google mobile maps application I was using previously. Unlike the Google app, the Yahoo one loads very quickly and does not take forever to refresh views. and it has a very nice way to select your zoom level. Every one of the "widgets" is content rich and has a great submenu that is context sensitive, so it gives you options for quickly and easily dealing with the content of whatever "widget" you are using at the time. If you haven;t checked out Yahoo! Go, you should. It is extremely impressive, and on top of that, it is FREE ;)
