Well, Crogge, I do as you told to look at your past posts, and found that what you do is not what you claim to be. For one you try extra-devel/testing and then overclocked your N900, and you're definitely one of the adventurous type. ^^

I understand your frustration when problems arise, but you know you enjoy the way N900 is. Of course I wouldn't recommend you to switch, here is a couple suggestions that might help.

1) You didn't say what MSN are you using. If you're using pidgin, there I can confirm you that its problem isn't related to N900 in any way. I encountered lots of problems with it I don't wanna whine at, I switch back to telepathy-pecan which is stable and great.

2) Regarding contacts problem with telepathy-pecan, first you must check whether you've flashed your eMMC when you flashed your ROM. You know, when they said there's new eMMC format with new ROM they definitely MEAN it.

3) You must know Joikuspot has some minor issue with your overclocked kernel, and even I'm not surprised to see it has other problems with stock kernel as well. Try mobilehotspot if you wanna build a wifi hotspot. I wrote my own script to make my N900 a wifi hotspot for greater flexibility and power-saving. If you'd like to try I can share with you.
