Well, I currently have an iPhone 4S, but when my contract ends in May I'm going to be switching to the GS4. Does anyone know how easy it will be to transfer iOS music onto the GS4, maybe based on usage with an S3? I was thinking of something that's close to the HTC feature that allows you to just drag your iPhone backup onto your HTC phone, which I may just get if iPhone to GS4 conversion is a hassle.Thanks, all help appreciated.
