New HTC Touch Diamond Firmware - 850Mhz radio ROM

New HTC Touch Diamond Firmware - 850Mhz radio ROM. We know that HTC Touch Diamond has a lack of support for the 850Mhz GSM frequency band in the U.S. Fortunately, XDA-developers forum has posted a new firmware that enables 850Mhz support in the HTC Touch Diamond.

With this ROM, your handset should be a quad-band GSM and 'US-friendly' smartphone. You can grab it from the forum's webpage. Note: Use at your own risk.
