I bought a curve 8320, it was t-mobile, but its unlocked so I can use on at&t. It has the 4.5 os, and I hate it, I want 4.2 like I had on my previous blackberry, but i cannot seem to find the right file to download to downgrade the OS. I have read many other posts about downgrading, and none have been any help. If anyone could throw me some info, it would be greatly appreciated, I feel silly having to ask.
i dislike the way that the texting looks and the contacts, and its laggy, i found 4.2 to run nicer, i dont mind not having video capture, i just want the speed of 4.2 back
Search the forums or the blackberry download sites for your old OS, then download and install it. Follow the upgrade/downgrade procedure link in my sig below.
