MaxLV: Just finished installing Cyan update for my Vodafone 520. Two updates, first one about 10 minutes, then a message to check for updates. Cyan update took about an hour to complete, and 30 minutes to update apps.
Note: standard Vodafone 520.
Great. Thanks for the info. updating our vnz 520 right now.
I didn't get the chance to roll back my 820 this weekend, so will do it next weekend (unless Microsoft fix this most annoying developers upgrade bug before then!)
