Motorola is to discontinue making phones for Symbian and will instead concentrate on two new platforms: Windows Mobile and Android.
Sanjay Jha, CEO of the Mobile Devices group at Motorola, confirmed what had until now been rumors to Michael Oryl of MobileBurn.
Motorola’s stake in Symbian was in UIQ, a part of the OS being cut following Nokia’s decision to move to an open platform.
A leading force in the US smartphone market, Motorola has seen it position threatened of late.
In November, Apple’s iPhone overtook Motorola’s Razr to become the best-selling consumer cellphone in the US in the third quarter of 2008.
Motorola is now expected to postpone any product launches until the end of 2009 to allow it to prepare its new Android devices.
