Re: DMR ?
No, Unihertz have said they're not locking it to any frequencies on the kickstarter comments. I spoke to them about it as I was planning to buy one (I'm an amateur radio operator so I wouldn't want it locked).
However I decided against it in the end. I'm not doing so much with DMR and usually use dedicated radios anyway, and it's only a so-so phone. And the software for DMR usually leaves a lot to be desired in these Chinese phones. So I decided not to bet on it :)
PS: I do have a Unihertz Jelly which is really nice for what it is, but part of what's so nice was the price of $69 in the kickstarter at the time.
