Updated from 7 a.m. EST to provide comments from Yahoo! in the third paragraph.NEW YORK ( TheStreet) -- I pleaded with Yahoo! ( YHOO) CEO Marissa Mayer not to ruin Yahoo! Finance when I heard the venerable finance portal was making a makeover. It appears my prayers were answered. Yahoo! unveiled its newest version of both Yahoo! Finance desktop and a new Yahoo! Finance app for Apple's ( YHOO) iOS operating system this morning, putting the property more in line with other revamped Yahoo! properties, including the homepage. Not only is Yahoo! Finance updated, there's now more real-time data from different providers to give users a much more "now" feeling when looking at quotes, tickers and news. Update: A Yahoo! spokesman emailed me to tell the new Web experience would be delayed, but the app is available in Apple's App Store Wednesday. At the top of the page, you'll see dynamic charting, allowing users a more visual and aesthetically pleasing experience when looking at financial news. Mayer has continued the theme of personalization, with Yahoo! Finance getting more personalized quotes and access to users' portfolios right at the top of the page. You can change the screen to go from your personalized look to stocks that you're following, which is done by clicking on a star next to the ticker. There's a place to click to bring up your personalized portfolio, showing how it's doing in real time.
