I have an unlocked HTC Hero that I got off ebay. It is the Telus gsm version, but it has hero rom build 2.73.661 which I can find no info on anywhere. The latest build on htc site is 2.73.405 but it says my s/n cannot use that one. Anybody know where this build came from?? Or what this means when android 2.1 is released, where do I get my rom..? Thanks.
