    need latest OS 7.1 for ATT Branded Blackberry 9900 that allows Network mode change

    I have got this ATT branded 9900 that doesn't allow Network change to 2G/3G mode when updated to a recent 7.1 OS. As it is known that 9900 battery stays longer if been run on 2G mode but now mine stays on 4G constantly. HELP!!!!!!!!
