There is some good news for HTC Touch Diamond users. Thanks to delevopers Touch Diamond is able to use 850Mhz GSM freq.
By default Touch Diamond is with tri-band support, but now is quad-band. You need Radio ROM update to do this. We don’t know why HTC didn’t include this feature, be cause HTC Touch Diamond has hardware support for 850Mhz and now it have and software thanks to developers.
The new ROM will improve battery life and signal strenght – nice huh?
