Iphone5s update ios1 version, ok?

it's very good. mine is that 1 is very smooth and user-friendly. iOS1 must be the last system upgrade of 5S, and the future system will definitely not be able to move 5S. However, after upgrading the experience by netizens, I feel that after upgrading iOS1 beat1 in 5s, the fluency is not bad, and there is no jamming phenomenon. It's just that the software is easy to flash back. After all, it is an iOS1 experience version. After the official version comes out, I believe that iPhone5S users have no pressure to use iOS1 system.
