It should be available in EU in Play store since yesterday.

Do some one tried the modded apk and microg services on jolla1?

Can confirm. The last update from the Google Playstore works fine on Tablet.

Sorry it took time to answer.

GUIDE to install MicroG to Jolla C. (Maybe works on Jolla1?)
#This is how I did this and got it working. Maybe all steps are not needed

0.Requirements
• For Linux, you need OpenJDK 6 or newer
• For Windows, you need Java SE runtime 6 or newer
• adb
• zip

1. AlienDalvik system needs to support signature spoofing so GmsCore can pretend the existence of the official Play Services to applications calling Google APIs.

• First we need to deodex. Full guide here
  

  • Download the zip and extract it somewhere
  • Grab a copy of the folders "framework", "app" and "priv-app" and put them inside "files" folder
  • Run quick_deodex.bat (or quick_deodex.sh on Linux) and wait while the files are being deodexed
  • After the script finishes, all files inside the folders you copied before will now be deodexed and zipaligned.

  Folders "framework", "app" ja "priv-app" are in /opt/alien/system/ path in Jolla.

• Next we need to inject framework.jar
  • Clone this Needle and extract files to deodexed framework folder.
  • Run python3 patch.py
  • Now you can delete extracted Needle files from framework folder.
• Then copy deodexed folders(framework, app and priv-app) back to phone(/opt/alien/system/)
• Restart AlienDalvik

2. Install latest nightly microG GmsCore, latest nightly GsfProxy(I installed also FakeStore, don't know if needed).
3.Verify that GmsCore and Phonesky has correct signature. Can be done from microG settings.


After that Pokemon Go should work.
I also installed MozillaNlpBackend & NominatimNlpBackend and configured them from microG settings.
I used evozi to download PokemonGo from Playstore.
And I made Pokemon Trainer account, not Google one.

Hopefully instructions are clear enough

EDIT:
ISSUES!

• AR mode does not work, because no compass
• Compass does not work^^
• No GPS error, when not moving for ~30sec. So stay in move!

Any chance you could upload those somewhere? Lots of steps could be skipped (unless there is something device specific in them, but should be the generic AD files)

Lets see I could do that soonish.

Thanks, I was trying to inject with that Needle script yesterday after your post, but JollaC shows up as unauthorized all the time in adb, so did not manage

Thanks, I followed these steps, but microG still claims signature spoofing is not supported. One thing I did notice is that there is no 'priv-app' folder in /opt/alien/system/. This is on the original Jolla phone.

I made own patch.py(check the link) because I couldn't get adb working like you.
