No flashlight in quick toggles, no support of danish special chars (æ-ø-å) in T9 dialer search. Such a pity! This means I'm not going to use the new firmware. Plus, I get a lot better battery from JellyBam. Camera acts better in stock firmware though.
I'm also on the lookout for the next thing. I want the best possible CyanogenMod support so I'm leaning towards a Nexus 4 - or the next nexus. Still, the S2 goes for 400 euros in Denmark and it continunes to be a very powerful device. I'm having trouble justifying 500 euros for a Nexus 4 when the device I have is nearly the same price and I'm still not facing limitations on the hardware side.
Only thing I can't get my head around on the S2 is why on earth it doesn't have a notification LED. My old Wildfire S had a notification LED.
I guess I will get a new device when 4G is rolled out properly in my area. There's a few months to go.
