According to the Seattle PI, both Cingular and T-Mobile are temporarily halting Motorola Razr sales due to a defect that has been discovered which sometimes causes calls to get disconnected.

Motorola said Friday the glitch affects only a limited number of phones and it does not expect any impact on financial results. "Motorola continues to ship new Razr handsets in volume to customer distribution centers and retail availability is expected to be normal across all markets by next week," spokeswoman Jennifer Weyrauch said.

Cingular Wireless and T-Mobile suspended Razr sales over the previous two days as a precaution so its customers didn't get stuck with defective phones. "It's virtually impossible to identify at retail which units have the defective component," said Peter Dobrow, a T-Mobile spokesman.

A component in the defective Razrs was discovered to be cutting off calls when the flip phones opened. Motorola was working to fix the problem and said no phones were being recalled.
