Sprint Nextel, America’s third largest wireless provider, will lay off about 4,000 employees and eliminate about 125 retail outlets after it suffered a net loss of more than 100,000 customers in the fourth quarter of 2007.

The layoffs and other cost-cutting measures are expected to save the company US$700 million to $800 million a year.

American wireless provider, Alltel, has extended its My Circle calling feature, where you can select 10 numbers from any carrier to call for free.

Alltel is now making My Circle an option for a greater percentage of its customers, adding My Circle 5 (add five friends to call whenever you like) to all plans costing $49.99/month

My Circle 20 (will allow you to add 20 friend) will be offered to customers paying at least $99.99. My Circle 10 will continue to be available with all plans priced $59.99 or higher.

Details about the My Circle service are available at AlltelCircle.com.
