After playing around with my new iPhone for a couple days now I think I want to attempt to Jailbreak it since with all my Droids I rooted those and generally that made them much better. Now this is an opinion since I am new to Jailbreaking, should I keep 4.2.8 and use sn0wbreeze or downgrade to 4.2.6 and use greenp0ison (i think that's the one).
