I know how you feel, I went through the same pain whilst waiting on my watch, people who ordered after me we're getting updates and I was getting nothing!!It's still grating me that some people on o2 have an update on the order and the rest don't. i.e. me.
It probably doesn't matter but it's a nice way of confirming there isn't a glitch or something equally negative.
Hang in there, I'm sure your order will be fine!!
