Hello, i'm new to this forum and as well to blackberry just got my storm last week and it was locked to verizon, and i was having the same problems.
so i was going to use crackmem wipe file to clean the phone a put on the OS that i wanted.
when i opened it up and saw "remove vendor.xml" i tryed to click it and it said something like it was removed. so before i decided to wipe my phone ( the sound of type in BrickMyPhone didn't sit well) i loaded up app loader one more time.
and low and behold it was there the new OS upgrade and not just the apps :haha:
