Right, I've downgraded from 8.1DP in anticipation of the rollout of the 1520 Cyan rollout in Australia not far away hopefully. Coz being back on WP8 after being on 8.1DP since it's been available sucks. And to top things off, backups using 8.1DP on the 1520 was not working for me and tried everything. So, I've lost quite a bit of stuff which I'm disappointed about. I'm hoping that Microsoft are getting their act together regarding the updates. There's been a few disappointments over the last few years.
