Jay and Al Fadi discuss that there is more than seven different Arabic Qurans , and none of them is from the time of Uthman (the third Muslim caliph).  They debunk the claim of Muslims that the Quran has been preserved,never been created and can't be changed;(Q 85:22,15:9).  In the time of Uthman; one Quran copy,  in the Qurashi dialect,  was chosen and all other copies were collected and burned.  Listen to hear more details concerning the subject.
