Hi all. I have an HTC Hero which I recently purchased. It was originally locked to orange but has since been unlocked. On using android market I have found that I don't have access to the google maps with voice guidance and also the amazon mp3 app. I have been told this is because my phone is still running on the 1.5 firmware. HTC have told me that an update for my phone is not yet available because it was originally an orange branded phone. Is there any way I can get round this? Can anyone help me? Any help would be greatly appreciated.
