Hi. Im considering jailbreaking my ipod touch 3g using blackrain (tethered), but im a bit jumpy 'bout it. Should i just wait unpatiently for untethered version or use the tethered. if i use the tethered then the untethered version comes out, how will i install the untethered version? (just jailbreak? restore than jailbreak? "unjailbreak" than jailbreak?) thnx.
