Regiiko: I've rooted my S2 using Brendan's instructions and installed CyanogenMod + Google Apps.
After making the phone reboot via CWM .. it's been displaying the 'Samsung Galaxy S II GT-I9100 (!)' screen for the last 2-3 minutes. :s
I have a nandroid that works, but ... what's up with it being 'stuck' on that screen?
Did you flash CyanogenMod twice as per the instructions? First boots can sometimes take quite a while as it rebuilds the caches. I've had much longer with some roms...
