Unfortunately no. Your phone doesnt support it.
a bit of Googling showed that no older phone in the market would get it
I am using Blackberry 9720 phone and wanted to upgrade the phone to the latest Blackberry OS. But when I search online or on my phone, I get a message that the phone is up-to-date and does not require any update.
The OS installed on my phone is 6.0 but the latest one is 7.0.
Is there a way, by which I can update my OS to 7.0?
