Review: Kyocera DuraXT for Sprint
The DuraXT has EV-DO Rev. A paired with a WAP browser. It's not the best combination for browsing the web, but I blame the browser and Sprint's horrid software more than I do the radio performance of the DuraXT itself. The browser is flat-out awful. The default home page is Sprint's portal, which is a disaster of links to content that costs you money. It's slower than a snail crossing a river of molasses. It's so bad, I'd say skip using the browser entirely. Use another piece of hardware, such as a smartphone, if the mobile web is important to you.
The DuraXT only allows you to customize some of the really basic things, such as ringtones, ringer IDs, screen savers, etc. As noted, you can alter the main menu between grid and list views, but you can’t customize to the way apps and folders are organized.
You can also change the input font between normal and large. The size increase is just enough to make a difference, but it doesn't go far enough for those who need very large fonts.
