I've reflashed emmc + rootfs (fiasco) and still doesn't work for me either. I'm so confused. my n900 just stopped recognizing my gtalk contacts. in the manual it says "When an existing account is activated, your contacts are automatically fetched from the account server and added to your contacts list". Why would this just stop working? Even after completely wiping the phones memory, it still doesn't fetch my contacts.

Edit: IM with gtalk is also confirmed to not be working on my n810.

I emailed nokia tech support, but now I'm wondering if it really is on google's end. I'm puzzled though because i can log into gtalk no problem with my palm pre and my ipad. Whatever is going on, i don't like it.
