[Avodah] Changing God's Mind

I understand the many answers given to: If God knows the future where  
is man's free will? But how would you respond to "If God is omniscient  
(and of course, knows the future), then how can His mind be changed?   
In other words, God knows what His decisions will be, so it's almost  
an oxymoron to say that your prayers may change His decision. If you  
maintain that they may change His Mind, then His Mind had already been  
made up to change.

Gut voch and gut luck (in responding to my impossible question).
