Ok, so today I receive a notification for the new RC29 update (I am in the UK) in my notifications bar, but i didn't click on it as I found out as I was switching off my phone (stupid University). Now when I've switched my phone back on, the notification has disappeared! (NOOOOOOO

) I've rung up T-Mobile and they said to come on here and ask all you clever people on these forums for any help, if possible! I have tried settings -> about phone -> check for updates and it says i'm up to date, but i'm not as i'm still on RC9.
If anybody knows of anything, thanks in advance!
