Yep, My Nokia Lumia (1.5 CPU, 1Gig. Ram) with 3 Gigs. of free memory crashes in the form of freezing/locking when watching Youtube, Daily motion Videos Via the internet explorer..This has happened 3 times watching 3 videos, the only solution is a Hard re-boot by removing the Phones battery and and re-starting..The internet stream is provided by W-FI, I have yet to test the clitch using any Carrier bandwidth..
