Not yet released, but you might want to keep on top of what Jolla is doing. They're a group of ex-Nokia employees that were laid off when Nokia went full-on Windows phone that were responsible for the linux-based Nseries N900 and N9.
They're set to release information on their first phone in November, it'll be a linux phone like the Nseries phones, and while it's not likely to have the massive app market for native apps, it should do all the things you say you're looking for.
They're also saying it'll run android applications, but that's just icing on the cake for you.
I'll admit to being biased as a N900 owner, but perhaps you'll be interested to see what they offer? At the very least to compare to the windows 8 phones out there as well.
