Alltel Wireless today announced the launch of Celltop, an exclusive, patent-pending technology, built on Qualcomm's BREW uiOne platform that offers customers an easier way to access, manage and organize a wide range of information already available on their Alltel Wireless phones. Celltop gives customers more control over their wireless experience through a unique and fully-customizable technology similar to the desktop on a personal computer.Now available on select Alltel Wireless handsets, and on all new phones by late-2007, Celltop is free-of-charge and features 10 "cells" that come pre-installed and via download. Each cell is a category-specific half screen comprised of graphics and text that provides shortcuts for wireless users to navigate through information and applications including: call log, weather, news, baseball, basketball, football, rodeo, stocks, text messaging inbox and ringtones.As part of Celltop's extensive array of customization options, users can also modify the appearance, presentation and organization of information within each cell.

Users will be able to further customize their Celltop experience through a wide variety of new cells that Alltel will roll out in the coming months via its Axcess Shop. Similar to "widgets" on a personal computer, Celltop is open to the developer community, providing unlimited user expandability of new and unique cells. Additionally, Celltop debuts an innovative ringtone management cell that allows users to seamlessly scroll through ringtones they've already purchased or browse and buy new tones all on the same screen. The ringtone cell also provides the ability to toggle through ringtones with a single tap - making it easier than ever for customers to
personalize their wireless phone. More information on Celltop is available at www.mycelltop.com.
