Well we reported a couple of weeks ago that the HTC Touch Diamond would be coming to the o2 network under the guise of XDA Ignito and it looks as if its in the stores now.
The XDA Ignito is in the current o2 magazine, where it states that it will be available in the middle of August and it seems as if they were right. From the picture attached, it looks like the only basic customization o2 have done is add their logo to the front of the device and add a blue TouchFLO interface option.
Other networks to have the HTC Touch Diamond are Orange, Vodafone and T-Mobile. Three will be making an announcement soon about the availability of the phone on their tariffs.
Below you can see the screenshot of the phone in the o2 magazine.
