I think I have figured out the fast boot issue. Maybe someone else can try to see if they get the same?
Ok this is what I have found (on my phone). I live about 10 miles outside of 4G and last night I was at a wedding that was in 4G, and my phone was fast booting fine all night at the wedding. My work has 4G as well and all day Friday it worked. Now this morning at home it's not working again (in 3G only area). I turned the wifi on to download some stuff and ended up rebooting for something and would you look at that "It fast booted with wifi on"!!!
So I have tried it a few times with wifi on and and it fast boots every time. For some reason the only time it's not fast booting when only connected to 3G.
