Hi, I just bought the HTC Hero on Sprint. I love the phone in every other way except one. My company uses RingCentral for our telephone system and they send all the voicemails I recieve in my email as a WAV file attachment (Specifically, the file is encoded with MS-GSM 6.10 Codec). Unfortunately, these voicemail files do not play on the HTC Hero and I have been unable to find a solution. Though Sprint says that Wav files are supported, these Wav files dont work. Its non the player, its is the OS which has limited codec support. Meanwhile, windows mobile phones, Blackberry, and iPhone all support this format without a problem. Can anyone suggest a solution - any possible way I can play my voicemails on the HERO. Otherwise, I will have to give it back and go back to my windows mobile based device. Is there any available audio player, or version 1.6 of android, or a way to load the right codec into the phone that could solve this issue? Anyone?
