Possibly, but the clear button does not show up for every kind of notification. Shows up for about 95% of the notifications. There are certain types I have had which do not have a clear option, but I can't remember right now what those were for. I will update the post if I figure it out. If you are referring to the standard types of notifications like a missed call, then yes, you should have the clear button showing. If so, then you may want to back up and flash again. Wipe system, cache, dalvik cache, and data/factory restore. Then you can either flash 3.3 or you can flash 3.2 first. Boot up once, then flash 3.3 on top of 3.2 with only wiping cache and dalvik. Flashing 3.2 first has helped some people that have had weird problems since 3.3 does not wipe at all.
