That's up from 106 million units this year, according to new research from Juniper.
The market for smartphones with an open OS will be driven, predictably, by the app store craze, according to the new report.
Overall, Juniper says 60 per cent of the current mobile OS market is based on open source software.
However, Juniper says the key is not whether the OS is open-source, but whether it's easy for a developer to design an application and make money from that effort.
The report says: "The combined changes of Apple's open route to the market and LiMo, OHA and Symbian's open-source OS approach have generated a tidal wave-like effect which even the economic downturn has been unable to reverse."
"There is a clear warning for device manufacturers - the choice of OS is now critical and market share will, to a large extent, follow application development. The unexpected side effect however will be a shift in the balance of power towards application developers and end users - they will begin to play the tune."
