A few weeks ago I asked my uncle who is on vacation in the US to buy me a Nexus One.

Anyway, I know that the official OTA Froyo update was released about two months ago and I was wondering if it were possible to receive the update notification from the Philippines. If so, what are the possible prerequisites for me to receive the update; like whether or not I should have a 3g postpaid simcard and other stuff.

Also, is there an official installation file that i can download from a PC for manual installation. I already know about the leaked Android 2.2 and I would really rather have an official release version.
