Hello. I am new to this forum thing! I see that a lot Hero owners have the 2.73 Build Number! Well my phone still says Firmware Version - 1.5 Build Number - 1.56.651.2 (and some more numbers) Software Version - 1.56.651.2 It seems to me as though I need an upgrade! I have looked through the forums to see how I can get to 2.73, but none of them gave a direct answer! If there is a post out there with this information, can someone be kind enough to post it here? Or just give me step by step directions on how I can get this?! I would greatly appreciate it! Other Information - I tried going to the HTC site for an upgrade, but it doesn't show anything there, only for Sync upgrades. Thank you in advance!
