Installed manually last night from a file I downloaded from AndroidCentral.
Install went well. Took about 5 minutes.
Of course, lost root, but was easily rerooted. Had to deodex again in order to theme.
Phone appears to be a bit snappier as mentioned above. Nothing dramatic. I personally never had any issues with screen redraws or general lagginess, but it does seem to be quite quick and smooth.
Battery manager FC's are fixed, timestamp in Txt msgs are now fixed. I never had issues with music player FC's or having to reboot for it to work, so I don't know if that's been resolved.
I too tried to check for updates, but got the same message most of you have gotten: "Your device is up to date".
Hence why I searched for the update.zip file.
Bootloader is 30.04 and kernel is 2.6.32.9-g5562e1w30471@il93lnxdroid08 #1
So far, so good.
Haven't tried using the 2.2 OTA SBF as I'm not sure if it will work or not, but I'm not willing to take a chance until a new SBF comes out.
