In brief The GSM version of Motorola's Razr phone is returning to US retail channels after a week long hiatus. Cingular says it has resumed stocking the device, which it pulled last Monday. T-Mobile withdrew the Razr two days later.

The fault lies in a sensor which can't tell if the fold-design phone is open or shut. A batch shipped to stores between January 16 and February 28 this year contained the fault, Motorola said last week.

The CDMA version of the Razr, sold by Verizon was not affected.

Apparently a bug that has turned certain models pink is a design feature, not a flaw.®
