I have bought mine from bestbuy on 28 June. It had green cloud issue. So i went to apple genius bar so they can check it out. They couldn't figure out and gave me refurbish IP4. I took that phone home and found out it also had this green cloud in the middle of screen. I went back to app store and wanted to return with full refund until they came out with upgrade. Guy told me that i cant return my phone even though i am still under 14 day. According to him, this phone is refurbish and cannot be return. So i went best buy and they told me this phone has a different serial number and they can't refund it either 
Any advise?
Thanks
