http://forum.xda-developers.com/showthread.php?p=13710179I had the i9020T KD1 and it was working fine for my i9020A. Any idea where I can get the KD1 radio you're talking about? 'Cause the i9020A KD1 is capped and the i9020T KD1 wasn't. I want to flash that back on. I'm on the KB3 right now and since KD1 is newer than KB3, I'd rather flash the new one since I think the new one is better on battery.
