Oh my lordy lord! Is O2's 4G usually that fast, or is Leeds (I presume) a special exception?
My mum is on 4GEE (salesman did a great job on her...) but she usually only gets 10-15 Mbps on 4G here. I'll wait for the iPhone 6 and get O2 if that's what the speeds are like rather than jumping to Three as I was planning.
Is your Mum in a "Double Speed" area with 4GEE?
I live in Derby and got well over 50 down when I was with them!
