I was wondering if unlocking vendor themes on the 8330 uses the same procedures as the GSM version? I remember trying to do it for the 8130 and had an 523 Error.

I too would be interested in getting access to the new Sprint Curve themes for my 8310, if possible.

You should have no problems... just follow the same old tried and true method:
How to Add Vendor Locked Themes - BlackBerryFAQ

I am under the impression that the later models (8110, 8120,8130, 8310,8320,8330), that the Vendor themes ARE not available.

I have seen reports that the java files for vendor themes were not included in specific updates.

I also have tried to unlock the vendor themes for the 8120 and the method that was used for previous devices did not work....

It worked perfectly on my 8310.

I have not been able to unlock themes on my 8130, just the tmo. one.

The normal method of unlocking themes has worked well on my 8310.

Must be nice!

I cannot get any theme to unlock on the 8120.....
