I am trying to update my Blackberry Q5 to the latest software. The only way I can do this is to use Sachesi, and update from there. However, when I check forth software on the UK Vodafone network, it states the upgrade for the Q5 SQR 100-2, my model is Q5 SQR 100-3! Are these models compatible, and can I upgrade my software from the SQR 100-2, or will this crash my mobile?
