For those that have already got the new MY SKY, it looks like an update is available.
The rollout version was:
Software: 11.25.00.R.R.98
EPG: SNZ.77.0.1.8
The update version available now:
Software: 11.33.00.R.R.99
EPG: SNZ.77.0.1.14
The whole interface feels faster but that could just be me excited that SKY could have fixed some of the teething problems :)
Not sure when it's being pushed out but forceful push gets the latest.
