Thank you both for the very fast reply :D
I'm downloading the correct OS right now so that should solve my first problem.
However, I checked and the phone is unlocked.
The phone application can be loaded with the Application Loader Wizzard right? So that correct OS should solve all the problems right away then
My phone has v126.96.36.199, so downloading the 'BlackBerry Desktop Software v188.8.131.52 '
should be correct right?
