Hello Jason,
Thank you for your inquiry.
First and foremost let me thank you for your keen interest in our line of devices. The HTC Touch Diamond is scheduled to be released in the US during the second half of 2008. Currently, there is no information regarding which carriers will be offering the Touch Diamond. The Touch Diamond has a microSD card slot and supports SDHC technology.
Jason, I hope we have answered your question in detail. Feel free to contact us again if you have any further questions.
