Rebooting galaxy s2 6 hours after ICS update...help please

[whiterose_uk]

Hi all,
my s2 has just started rebooting itself over and over and im not sure what steps to take so asking for some kind advice please.
I updated to ICS via kies around 12.30 this afternoon from gingerbread (after backing up my phone). My phone is branded vodafone but unlocked and is using an o2 Sim.
I cant tell you any build numbers etc.

The furthest the phone boots is as follows... turn on, the booting logo, sim card unlock pin, pattern unlock screen, once unlocked the screen is black, after 30 seconds or so, it reboots and does the same again but minus my sim unlock screen. It reboots to the pattern lock screen instead.

Ive barely used it all day other than to take a look at whats new, i was about to begin a txt message when it randomly rebooted and just restarts.

Thankyou for taking the time to read... id appreciate it if you could also take the time to reply, even if its just hello

Hello !!
It is advisable to do a factory reset after flashing ICS to remove any residual left over from GB. Hold power, vol up and home keys together with phone switched off and hold until you see the green android. Then use vol up/down keys to select "clear cache" then "factory reset".
