I'm now rocking GingerBread

After I got an Over The Air notification to say 2.3.3 was available for my Google Nexus One, I decided to take the opportunity to change my gmail email address from googlemail.com to gmail.com.
When I did this some months ago now it broke some of my apps on my Nexus one due to sign in details that could not be changed, the only option to me was to wipe the phone and start again.

So this is what I did, restored factory defaults on the phone then change my gmail.com details, then set the freshly wiped phone with the new google details.

Then i wanted to download gingerbread via the OTA update but the notification had disappeared from the phone.

I then looked to see if there was a way of forcing the update or manually installing.
I came across the code to force the phone to check *#*#2432546#*#* (*#*#checkin#*#*) which i put into the phone dialler, got a msg back checkin successful , but still nothing.

I then found a site detailing instructions on downloading the gingerbread update then putting on the MicroSD card and then rebooting the phone in a loader mode.
I cant find the original site but this link details what i did. androidcentral.com

Found more details on the Google Mobile Help Forum some report google voice can break on the Nexus One, cant get this in the UK so im not bothered about this.
