Is it possible to update HTC desire to 2.2 with unrooted? I bought a new HTC Desire (will arrive in a few days).
The phone is not branded (or unbranded) will arrive with version 2.1, and I want to update to 2.2.

After a lot of reading I realized I need to create a goldcard. So I bought a 2GB microSD card and I will create the goldcard when the phone arrives.

I also read about rooting the phone, which means (from what I understood) to flash the phone's ROM.

What I want to know is do I have to root the phone in order to update to 2.2 ???

Thanks a lot !!!
HTC provide OTA-update to 2.2 for HTC Desire. You don't need any special (root or goldcard) to update your phone. Just connect your phone to Wi-Fi or 3G
