i had the same problem, got mine fixed.

use the extras-devel n install msn (haze) 0.9
before i log on or activate it, i use msn's own live messenger to log on then log off. then i activate msn haze n it started working again. same trick didn't work when using pidgin. don't use pecan either.
i found out it happened everytime i logged on else where while n900 is still connected to msn, then i lose the contacts.

i find msn butterfly from devel works better than haze now. at least for me, n doesn't have the no contacts problem period

The camera bug is annoying when changing exposure to 0.5+ when you are using manual ISO.

Yeah i think so too. Just on wifi, the back of the n900 get warm but in pr1.1.1 doesn't

Has anybody an answer to my problem. After PR1.2 I get alot of blank pages in the web browser(not Firefox)?

+1 Email notification sound playback is buggy
+1 Screen glitches when answering calls (annoying)
+1 Video recording and playback not smooth (was better with 1.1)
+1 When FM transmitter enabled, it sometimes plays music through speakers at random time for 1-3 seconds
+ RingTone playback buggy

Opinion of 1.2 ? Made my experience with n900 worse...

Here is the Bug Report. Please Vote if you still miss this fundamental feature: Bug #10332

They all are when the CPU is loaded, I have no idea why it keeps doing that. I get that all the time, someone needs to ramp up priority of the audio subsystem. Who thought browser loading should take CPU cycles from the player?

Very rare. Only once thus far. I keep Phone pinned to Portrait.

My playback is better, if a bit slower to start. Recording is the exact same. Maybe you have a small issue?

Same problem.

Also, I have gained an insane autonomy with 1.2 relative to 1.1.1. Not sure why, but I do. When low usage, I get away with 10 minutes of charge when battery is low for the day.

Has this one been noticed:

Open the main menu (that lets you launch programs)
Scroll down to the bottom so the icons won't move up the screen any further
Press your finger directly on an icon so it glows
Move your finger up so that the icons move about 10 pixels (if you move too far, the kinetic scrolling will kick in and move the icons back..)
take your finger off the screen

Notice that the icon is still glowing as though you still hold your finger..
And in a few seconds more, the menu will flick into rearrange icons mode

I´m just wondering here. Could someone explain why they optificated quite many things on n900? When we were waiting for 1.2 there was couple of messages from nokia employees that hinted about testing problems because of optification. Now it seems that there is some multitasking problems with browser + music on some people.

I have over 50% free space available on my rootfs. WOOHOOO. Why? If extra apps are optificated and some of them take little space from rootfs then why waste fast memory. Isn´t rootfs right now just sitting there for sake of it.

I have had a lot of trouble after pr 1.2 and the newest eMMC image. I have not managed to pinpoint what the problem was/is. I have re-flashed several times; both images. The first couple of times it worked great for a day or two, then the screen and phone behaved like it was "infected" erratic behavior of the screen and the solution for me (as i am no Linux guru). I manage very well in the MS sphere which is my profession. That said. Id like to say this if it can help anyone. After this re-flash, both images, the phone worked very well for several days.

My software/package status is (alphabetical order):
agtl 0.6.1.3-1
bluezwitch 1.0.0.-2
conversations inbox desktop widget 1.1.1
currency converter 0.8-7
cuteexplorer 1.1.1-1
fmms 1.1.8
leafpad 0.8.17le-0maemo1
martian memory 1.0-3-fremantle5
mobile maps 9 demo 7.71.0 / nordics
pyreciepe 0.5.1-3
simple brightness applet 1.1-1maemo0
theme marina (in use) 1.095
wifieye 1.0-3

No i dont think this will be an eyopener for anyone, but it might help someone get closer to which code thats a killer for the new pr 1.2.
