You can cross another resolution off the smartphone display list:
The third device from the Z5 series is the Xperia Z5 Premium, which includes the 5.5" 4k [3840×2160] screen, a 3,430 mAh battery, and the ability to expand its 32 GB of default internal storage by up to 200 GB through microSD cards. The 4k Triluminos IPS display promises to have a high color gamut, higher contrast and higher sharpness, as well. In the few moments I've spent with it at IFA, the screen did indeed look crystal clear.
[...] Xperia Z5 will launch globally in October this year, while the Xperia Z5 Premium should arrive a month later, in November. Both single-SIM and dual-SIM variants will exist for both models.
Some lucky Sony executive is shoving the Xperia Z5 Premium in his Google Cardboard. Next stop, the world's first 5K (5120×2880) smartphone.

Do you know the Hz of typical smartphone displays? Is it 60 Hz?

Yes, 60Hz is standard. Which could be considered slow for VR, although 60Hz with low persistence may not be bad (I think only Oculus runs faster).

2160 × 1200 at 90 Hz for the first consumer version of Oculus. I was surprised they didn't spring for 2560 × 1440.
Given that 144 Hz and 200 Hz displays are a thing, I doubt it will be long before a ~4K VR product targets 120 Hz and up, although whether graphics cards will be able to push that many pixels is another story.
I haven't looked at many reviews of Cardboard/smartphone VR. Should do so to see what others are saying about 60 Hz strapped to their face.

I have no interest in smartphone anything, I might look into OSVR though- the first dev kit is shipping to developers now, at 1920x1080 (same as oculus DK2). I had high hopes for oculus but most of that died when facebook bought them out. I guess it's likely they'll put out some good hardware before getting "monetized," (spywareized) though, since there is still money to be made selling the product. Imagine how annoying adds could be on a device that can track your eye movement.
I think you're right that displays are getting ahead of GPUs in VR. Because of the high refresh rates, VR is extremely intensive in the GPU- though it also needs lots of pixels. I wonder if they didn't keep the pixel count lower just to make it a little easier to find GPUs that would run it.

I'd be happy to see the amount of details lowered ("Ultra"/"High"/"Medium"/etc) in order to push 120 Hz at high resolutions. Smart use of lighting, textures, and LOD can deliver nice results. As someone else said, CRTs have been able to do 200 Hz+ at high resolutions in the past... at the cost of graphics complexity. I think the immersion/sensation of feeling like being there will be more important than the graphics detail. That necessitates keeping latency low at the cost of graphics, and even when graphics improve, the focus will be on keeping that high and stable frame rate target. The push for FreeSync/GSYNC on new monitors and laptops would seem to confirm this trend.
I think the Facebook hate is waaay overblown until we actually see DRM/ads/tracking on the consumer platform but I accept that some will never support the Zuck. It seems there will be good competition in the VR market, so you'll be able to blow off Facebook/Oculus and Sony, or even skip HTC/Valve for a device from a fourth party. Not to mention similar devices like Microsoft HoloLens and Google Glass 2: Don't Hate Us.
