Have just started using a Lumia 920 and followed the App Studio method to update to GDR 3. Now I believe at present by warranty stands void! My question is, when the official release for GDR 3 does come out & after updating my phone with that, will it restore my warranty?
Is there a method to revert to Amber should I need to hand over my phone for warranty issues?
Please do shed some light on these queries.
