Sensation support on 3(uk)

[Sensation225]

Hi im needing some assistance...i recently just updated my sensation OTA (just last night *28/09*) and ever since i have my phone keeps rebooting itself...I have tried a hard reset twice and this still continues. I have the factory settings (i havent used any ROMs for my phone) and since the update my phone is unpredictable sometimes the phone can last 2mins sometimes it can be upto 2hours before it crashes and reboots....

Android version:2.3.4
Sense:3.0
Software number:1.45.771.4

dont know if this helps....
