Think Ive bricked my NS updating to 2.3.4. How do I fix?

[Guest TheBishopOfSoho]

Hi there, I previously had CM7.0.2 installed on the phone, but wanted to try out the Video chat on google so through ROM manager I installed Stock 2.3.3 fine. Phone booted and loaded normally. Then I stuck the 2.3.4 update.zip into the root sd and installed that through the recovery and that seems to work fine but now when I start the phone its stuck in a boot loop with the nexus logo and I cant get it working. Any ideas what I might have done or how to fix?

Sorry, Im being an idiot, once I wiped the data and cache it loaded fine. Sorry!
