I don't have a htc phone and you cant do it with ipod touch that i am aware of. ipod classics and ipod nano 1st gen and 2nd gen. i recommend get ps3key, ps3 jailbreak, ps3 break. much easier and neater. i also do not use hermes payload, i use one of the original payloads that had backup compatibility. Meaning I still have to use a ps3 game to boot back ups.
You are just going to have to dig around and found what you need. And use trial and error.
