Upgrading Unrevoked Desire from Eclair to Froyo I'm currently running my HTC Desire on 2.1 (O2 branded from the UK, if it makes a difference) which has been rooted via Unrevoked. I've just now been prompted to upgrade it to what I assume is 2.2 via an OTA update. I'd quite like to do this but I'm assuming this will cause me to lose my root. Unrevoked seems to now say it supports 2.2 as well as 2.1 so would it just be a matter of doing the OTA update and re-rooting with Unrevoked? 

Also, I've never performed an upgrade before, do I lose all my apps/data/configs? How long does it normally take?

Thanks.
If this is a standard OTA update then you shouldn't lose anything at all, and the update should take less than half an hour, just make sure that your battery is fully charged before you start. All your apps, data and configuration should stay. The only exception to this is where things have changed between Eclair and Froyo, so some of your apps may not be compatible with Froyo (though it's been out long enough now that's very unlikely).

Yes, you will lose your root status, but should be able to root again afterwards, provided your chosen root method works on Froyo, or you can find a different rooter that will work if not.
