The problem is that you cannot use this mechanism to actually transmit information faster than light because you need some other kind of means to know when to observe your entangled photon. If Bob and Alice have entangled photons, Alice has no way of knowing if Bob has sent her a message using her photon because if she checks it to see if the superposition has collapsed then she will herself cause it to collapse if it hasn't already done so (thereby preventing Bob from sending a message at all).
This means that you're left using some alternative means of communication (radio, etc) which itself is limited by the speed of light.
I am only an English teacher, so if this is silly, please excuse.
Why can't Alice and Bob have a prior understanding about when to observe? Alice tells Bob, "I will take my measurement tomorrow at 4 pm, thereby collapsing the entanglement. You can make your measurement after that."
In this way, they can have FTL communication the next day, can they not?
