Just a curious post.  We were using someone's iPhone 5S (on 2degres) and put it into WiFi mode due to their data they had carried over.  Tried to watch a video with Youtube.  It works if you leave it in auto ie 144p resolution.  If you change this to 1080p or 720p or 480p it plays a few seconds and then spends the next 5 minute buffering and it does this repeatedly.  This is a bandwidth issue with the iPhone 5S?  

I did try and use my own phone which is also on 2degrees using mobile data directly and it worked fine with 1080p.  

Thoughts?  Cheers.  :)
