when flash is officially out it will hang in the general section for a bit and then move to this section. this is support and troubleshooting. the general section is not setup for support.
until then, all "where is flash!" posts will remain here. this site does not need a bunch of unecessary posts.
also this is not "hidden" you found it just fine.
if you need any more questions asked, send me a PM. otherwise lets keep the thread on focus.
saying this, a poster at XDA stated he/she just received the flash update.
