I made the leap and updated to PR1.3 OTA, and noticed some issues.

Some of them seem rather localized to certain apps or subsystems, and I wonder if some could be downgraded?

Notably, the MfE sync not setting alarms any more (there is a thread on this topic)

Is there some way to know what library/package/component that is, and downgrade that to the 1.2 version of it?

Secondly, I'm having an odd issue with WiFi... WiFi itself works great, but if I try either of
a) JoinkuSpot
b) Mobile Hotspo
c) A script that sets up an ad-hoc networking on the phone
...neither of them work, notably, the DHCP is not giving out the right IP. The phone logs that it is handing out some IP, but the device actually gets some other totally different IP, and hence doesn't connect properly.

I guess the latter (wifi) problem is caused by me running kernel-power (1.2?) on top of PR1.3... or something?

I don't want to totally reflash (too much custom crap done) and not a fan of the idea of downgrading completely to 1.2 since 1.3 brings several lovely fixes (like mail client speed and pulsaudio stuttering fixes)

Any help appreciated
