Is firmware backwards compatible?

I've downloaded the latest firmware for the 8700 (8700M_PBr4.2.1_rel149_PL2.3.0.77_A4.2.1.94_Vodafone_UK.exe).


Is this 100% compatible with our BES 4.0.7?


Also, can we deploy firmware Over The Air, or do we need to upgrade to BES 4.2 to do that?

Re: Is firmware backwards compatible?

Version of Software on the Device has nothing to do with what version of the BlackBerry Enterprise Server, except for some features not being available to device if the device has much older version.


In order to upgrade the software on the device you will need to use the BlackBerry Desktop manager to install the Device software.
