Meanwhile

My Nexus One has retired. Again. Hopefully the HTC will send me another replicant soon.
While waiting it back I decided to change the system to a Tattoo on my old good Kaiser because I get tired of that blurry resized image and already get used to the sharp and crispy off the Nexus.
Tattoo system has the same resolution as Kaiser - 320x200, so it should fit.
The install process went smoothly (I took the source from here). Then I found the Wi-Fi does not work. I took an update from here, but standard /sdcard/andboot/androidupdate.tar update did not help. Comparing I found out the sysinit.rc is still different, and placed it manually. Then WiFi started working.
Current issue - the market client can not connect to the server, throws
DEBUG/vending(5478): com.android.vending.api.FatalCommunicationException: Sent a bad request.

Repair update: HTC sends the replacement phone overnight in the same day as they receive the broken one. Outstanding!
