Cingular Offering Free Extended Battery for the Samsung BlackJack
by Ed Hardy -  2/26/2007

Not too long after Cingular Wireless begin selling the Samsung BlackJack, some users began to complain that this smartphone's battery life is too short.

Originally, this model came with two standard batteries. More recently, however, those who buy a BlackJack get one standard and one extended battery.

To make it up to those who got their device with only standard batteries, Cingular is now offering these customers a free extended battery. A cover designed for the later battery is also included.

Only those with IMEIs between 352794010030189 are 352794012269959 are eligible for this offer. An IMEI is a 15-digit number that can be found either on the packaging or behind the battery on the device.

To request this free battery, visit Cingular's web site.
