I downloaded the OTA zip file from the Internet and renamed it to UPDATE.ZIP and put it in the top level directory. I did the manual boot (down volume plus power button) and loaded the new update. That is a manual update that results in the exact same update as if VZW had sent it to my phone. Thus, there is a manual option. I did my Froyo update in the exact same manner a year ago.
Did it manually. Worked fine.
don't you have to go to the android recovery in order to recognize it?
Verizon has pulled back the OTA 2.3 android update. Check the link below.
