Man I really wish BB10 had come to the market earlier. I honestly don't doubt it'd still be around today if it wasn't for the fact it entered the market so late. BB were too busy dragging their feet for years after iOS and Android hit the scene. If they started work on BB10 as soon as the iPhone was released, I think we'd still have BlackBerries and more importantly a third platform. The Apple/Google duopoly benefits no one except Apple and Google.
I still have a Q10 somewhere, it's such a nice phone too.
There's still a lot of things I can't talk about because some of the people who I worked with, who are great people still work there.
Internally, 33% of every dollar went to the Blackberry Wireless division because Blackberry was created before commoditized mobile chips existed. In effect, this means we paid for the chips, paid an extra fee to unlock it just so we could flash our software.
It was an ongoing battle between the spec for Bluetooth being released and having our own version, validating it against every single thing out there that could connect to it and then shipping it out. This made it extremely pricy to deliver a feature on the wireless stack and often things just weren't supported which came with the original chipset.
It's difficult to turn the ship around without just firing everyone involved and going "just grab what's there just like Android is doing"
I still have a special Z10 that I was allowed to keep after working there.
It's a red Z10 running an unlocked bootloader which allows you to hold down volume up-volume down and boot into Android 5.0 environment.
Sadly "Project Exodus" was considered inappropriate at the time just like the original Android Player on BB10 since it was considered inappropriate to think anything other than BB10 was the greatest thing since sliced bread.
Edit: 2 years after I left, Blackberry devices became Android devices... so I guess I was ahead of the curve or something?
It is probably not possible, you have to unlock on premises using a signed version of the tooling on a beta version of the OS on the device.
Your key2 probably has a customer version of the OS running it, so it would never be able to be unlocked :(
I argued about this but eventually the security of the "ecosystem" takes over the usability of unlocking older devices so they can be used for something else.
