It's stuff like this that makes me wonder why I'm still with Verizon. Alltel Wireless just introduced a new app for its mobiles called Celltop. Esentially, it's a way of bringing widgets (aka cells) to your cell phone. Each "cell" takes up half of your mobile's screen and can display stock info, weather, news headlines, or something as simple as your call log. What's extra cool is that Celltop is open-source, meaning anyone with the know-how can develop their own "cells." Celltop is free and available today—the catch is it's only available for Alltel Wireless subscribers. Stay tuned for our own hands on with the app.
