| | Re: Change carrier software
What exactly are you trying to do? You can't change the opening splash screen if that is what you meant. The OS can be from any carrier as it is developed by RIM for the specific device and makes no difference.
Do you have a BB plan from your new carrier, whomever that might be (and please update your profile to show the carrier). You need that for all of the BB related services.
Are you sure the device is unlocked? If it is indeed unlocked, and the carrier is GSM, then it should work when you put in their SIM.
If the carrier will not activate it because it isn't their device, then that is a true carrier issue and no amount of software can change it. You need to discuss it with them.
