I'd also be interested in this, and would like to know from the 10.2.1 crew ( telstra aus haven't released it yet) if you have loaded sfdc 1 and whether it works, and if so what the performance is like, thanks.
Just upgraded my phone to 10.2.1 and was able to install salesforce1 android app.
It runs ok, no crashing, but definitely doesn't feel as smooth as the BlackBerry native "connect to salesforce "app put out by bb.
I just hope that they iron out the bugs with the native app soon, as having a good sfdc native app will be critical to driving the enterprise up take of BlackBerry devices that bb mgmt is so keen to have.
