i'm using ipod 1st generation with ios 3.1.1. i found spirit best for jailbreak that. it takes no time like other methods.. try it if u r using the same device. it really saves ur time.. here's the link. http://spiritjb.com/
dont know much about snowbreeze. ya there are lots of those. i preferred that because. it takes jst a minute or less than that. and the mail point is that it is untethered jailbreaking which means u can boot ur ipod touch and it still jailbroke. thanks for the information about snowbreeze, i'll definitely try that someday.
