Yesterday saw the launch of the HTC Desire HD and the HTC Desire Z, not to mention an upgrade of its interface, Sense UI and the cloud-like Sense.com. But what about older handsets? Will they get the upgrade as standard? The answer to that is possibly, but only for certain models.The new UI works in conjunction with HTCSense.com, so you get cloud syncing of contacts and messages, phone recovery tools and easy remote interaction with your phone. Useful if it goes walkabout. There's also improved mapping, DLNA support and Facebook face tagging of photos before uploading.However, the interface is designed for higher end handsets and requires Android 2.2. Already that rules out a hefty chunk of HTC's back catalogue. But it does leave the door open for the existing HTC Desire.Talking to TechRadar, HTC Executive director Jon French confirmed that it is 'looking at other handsets' when it comes to porting the new UI to older devices.'[Sense UI] depends on a technical standard, where it has to support the new services offered by HTCSense.com. We're launching that on the Desire HD and Desire Z, and it could be that we roll it out to other devices later on.'So keep those fingers crossed, you just might get a 'new' phone without any outlay.
