On another note, updated to 2.2.0 last night. Will see how it goes, i've had the occasional reboot and still not attempted to see if it'll behave with an sd card yet.
No only one SIM is 4G. The other is 2G-only.
They are both 4G
What it means is both will connect to 4G suppliers using a 4G SIM, but only the card in slot 1 will be used for mobile data.
Of course - but looking at the pic on their website, the gap seems larger than normal; it seems to be part of the flat surface too.All screen protectors leave a gap because the glass is curved at the edges.
