HTC has just unveiled the Touch Diamond2 and Touch Pro2, upgraded versions of the Touch Diamond and Touch Pro respectively.

The Touch Diamond2 features a larger 3.2-inch QVGA touchscreen display with touch zoom bar, 5-megapixel camera, and a new and improved version of Touch FLO 3D.

Design-wise, HTC decided to go back to basics with a slightly less flashy but nonetheless still stylish casing for the Touch Diamond2 as compared to its predecessor.

The Touch Pro2, on the other hand, is the more impressive upgrade of the two.

It features a large 3.6-inch WVGA display with touch zoom bar, an improved QWERTY keyboard design, the new TouchFLO 3D with Straight Talk (a new UI that combines all communications into a single interface), and a new feature that activates speakerphone functionality when the phone is turned upside down.

It also comes with a mute button at the back so you can easily put it on mute mode when using it as a speakerphone in a conference.

It’s also now housed in an even more stylish design and features a tilt design so that it’s ergonomically easier to use as well.

The only thing that got left out at the upgrade party is its camera, but I guess 5-megapixels is still pretty impressive even by today’s standards.

Look for both phones to hit the European market sometime in the second quarter of 2009.

Early summer is the target release date for major markets across the globe.

Pricing is yet to be determined (with or without a cell phone plan), but if I were you, I'd start saving up right now as these two look tempting to say the least.
