Hi! I've got a Sprint Hero with Android 2.1 (.6 and not .5 as required for unrevoked). All I want is root access (no custom roms) for some applications (mainly WiFi tether). I'm a complete noob to rooting and what I gathered from the guides is that all data is erased. Is there any way (regardless of how complicated) such taht I don't lose any data/apps and just gain root access?
