Well after jumping ship to the Galaxy S4 for the past 4-5months I am thinking of coming back to Apple. I have enjoyed the S4; especially the screen which truly is amazing. However there is, in my mind at least, no denying that Apple products and Apps work smoother.
I have noticed that the Samsung stutters sometimes especially when opening the gallery and whilst I am aware these are first world problems, it has been frustrating this first world resident

also I have to admit I never managed to get any of the hand waving; eye tracking functions on the S4 to work.
One thing I am not looking forward to, aside from the amazingly high price is the inability to order the 5S before launch. I am looking to drop a lot of money and hate being made to feel privileged for the opportunity to do so. Has it been mentioned when the online ordering will beginning (midnight or 8am?) also what do people think the turnaround time would be for the online orders; would it be 24hrs or 4-5days job?
One last question I am slightly confused with the various LTE bands; but I am off to US next week is buying an unlocked handset over there an option for us in the UK (thinking of using Three or EE).
