I have downloaded and installed IOS 4.2.1 on my Ipad 64 wifi and Iphone 3GS very easily ( using shift update , which kept all my data and settings) All is really great except the mute button does not now work on my iphone 3GS OR Ipad ( i.e the new lock switch function) .It does show a graphic Icon of the speaker crossed out but does not shut off the sound. Maybe a bug?However it had been working fine with the earlier 4.2.0 GM ??hopefull
how to rip dvd to wmv can solve itI can't see it having a metal back (which would act as an RF shield) after all the problems they had with the metal back on the iPhone 1 and the antenna problems of the iPhone 4. You cannot devy the laws of physics and get RF to go through metal at all the frequences the iPhone uses for it's various radios. If anything I would expect them to ditch the steel band antenna of the iPhone 4 and revert to an integral antenna. An RF shield on the back of the phone would mean you would get variable reception for the phone/GPS/WiFi/bluetooth depending on which way you were facing. Steve Jobs will then probably tell us to 'don't face that way' or some other classically stupid comment. A metal back would also negate any possibly to have NFC in the same device.
