HTC originally made the promise when they released the HTC Touch Pro 2 back at the MWC (Mobile World Congress) in February that the Touch Pro 2 would be fully upgradeable to Windows Mobile 6.5 when the binaries went gold.
To their word, HTC have come good with their promise and are rolling out official updates for both the Touch Pro 2 and the Snap. So Touch Pro 2 and Snap users may be able to get a ROM update to 6.5 very shortly. The reason I say ‘may’ is that it also depends on your mobile phone network. e.g. If you are on T-Mobile, they have a T-Mobile special branded ROM and T-Mobile may turn around and say they don’t want to provide the new ROM due to support issues that might arise from it.
So unfortunately it’s still not 100% official, but at least some good news for Touch Pro 2 users. Unfortunately no news yet on the HTC Touch Diamond 2
