I am not sure what took me so long to realize this came in 10.2.1 but I have been wanting this feature for ages. BlackBerry now resizes the text in emails you receive to fit the screen if you zoom in on the area. Its not 100% but it does work. You simply just zoom in on any text and it will resize the text and justify it to fit the width of the screen. I still does not seem to do it by default when you open up an email that is bigger than the width of the screen but it does work!
Check out some of the examples I took and share some of your own with the new image uploader in the comment section! Thanks Blindguy for pointing it out in the forums!
