HTC Desire owners, rejoice! Android 2.2 (Froyo) is set to arrive this weekend with all its Sense goodness. There’s a slight catch though. This timeline is applicable only to folks who purchased unlocked handsets. Carriers, who are notorious for taking their own sweet time, will determine the fate of locked (branded) handsets.

This update will also introduce some tweaks to HTC’s proprietary Sense UI. “As well as including the complete set of Android 2.2 features, the update will contain a few special additions of our own through the latest iteration of HTC Sense,” said an HTC spokesperson to CNET.

While Desire owners across Europe will begin receiving Froyo tomorrow, HTC Evo owners in the US will have to wait slightly longer. Don’t worry though, Sprint phones will still be the first to get Froyo in the US. Sprint has announced that it will begin rolling out the update on Tuesday. However, not all users will be getting it immediately. Thanks to the phased deployment, you might have to wait til mid-August to feast in the Froyo goodness.
