One tiny problem with this is that there is no 4G service is currently available in china. China mobile also does not run a standard 3G network they run a proprietary 3G network standard that only chinese phones made for their network can run on, it looks like the 4G is going to be proprietary also, 4G/TD-LTE and 3G/TD-SCDMA. I dont know how they are going to be ready to have 3G and 4G ready for the iphone by the end of this year. So this means those iphones to be sold by china mobile will be using the proprietary 3g and 4g standard that cant be used outside of china. Many customers who travel will be very upset when they realize their iphone data network wont work outside of china
