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.....

The themes unlocked great for me, but some of them aren't worth keeping. Can they be removed by reversing the same process? Thanks in advance ....

Just curious if anyone has tried this on the 8330 with Verizon?

it should be the same procedure... see the first post in this thread and follow up

If I were to follow the steps to unlock the vendor file, I'm guessing that the latest version of the handheld OS for the AT&T 8310 does not contain the new themes for Sprint's Curve. If that's the case, is there a way to insert them into the OS before it loads onto my phone?

How did you unlock them? Did you use the method from above? I'm afraid of getting the java error and having to wipe my BB again.

I have done it on 8330 with Telus and the themes work fine

Yes, it works for Verizon 8330 as well except that I couldn't find the .alx file until I upgraded to the 4.5 OS that is now circulating.
