Two issues with iOS5 on 3GS

[nebo1ss]

I installed and jailbroke IOS5 on a 3GS old Bootrom and seem to have two problems. (1) Ibooks not opening. It tries and then immediately closes.
(2) I do not have the Camera button on the lock screen.

Is anyone else experiencing these issues and are there any workaround for them?
