Windows Phone Thoughts: Firmware Update for 2125 - No AKU2

There appears to be a ROM update for the Cingular 2125. Rumor has it that it addresses some 3G SIM card issues. Now before you rush off to flash your phone (I haven't yet) consider a few things. First, it doesn't have AKU2. Second, it doesn't appear to upgrade the OS at all. You end up with the same ROM version. The only thing that does change is the Radio Version. Mine is 4.0.13.20_01.09.01. The new one is 4.0.13.21_01.16.01. Cingular has no trace of this ROM on their site. This comes from HTC's site which is notorious for not explaining anything. Worth wiping out everything and starting over? You decide. :)
