I use a simfree Wildfire on the o2 network in the UK and at the moment there is still no update available I have contacted o2 but I have not had a reply from them as of yet but when I do I will post there reply here.
My advise is to check with your network provider before trying the factory reset, see copy of HTC's email below dated the 07/11/2010.
Thank you for contacting HTC Customer Support.
The 2.2 is available for the HTC Wildfire.
This will be received via FOTA (firmware-over-the-air). This means that the individual network providers will send the update to the devices from their servers.
There is no possibility to pinpoint the exact time when a certain device will receive the prompt to update.
You can try a factory reset to try and trigger this but please be aware that this is not a guaranteed way of triggering an update and will restore your phone to the original factory settings (data will be wiped).
Sincerely,
Karolin

Seems HTC have no idea of what they are doing just received this email at 3:05pm 07/11/2010 see email below.
I do apologise for the misinformation.
What was flagged to me as a FOTA update for the Wildfire is actually just an add-on to improve certain functions.
I have investigated when/if the wildfire will receive the 2.2 update for you and at this moment and time we do not have any official dates or comments to pass on.
If you would like to see the FOTA for improvements please view the 8th listing of this link:

Again my apologies for the misunderstanding.
Well got a reply from o2 uk today they say as the Wildfire is not in there portfolio they would not be getting or releasing any updates from HTC for the Wildfire via the o2 website in the UK any updates must come direct from HTC and not via o2.
