the android doesnt need jailbreaking because it natively supports homebrew apps and giving the end user the choice to fully own every aspect of their phone. not to mention a STANDARD sd slot and a usb/hdmi interface. its 2011 if you give me any device with out an sd slot or mini usb you should be out of the game (its a user controlling tactic). luckily traditional convention doesnt apply to apple, they have their marketing moniker to fall back on, who else could sell you a notebook with out a user replaceable battery, patented proprietary ac adapter, no dvd drive, and a proprietary standard(does that even make sense?) mini dvi comm port interface with intel hardware for twice the price of the pc equiv and people will buy it. you say you want OSX? run linux. anyone who says osx doesnt crash is lying. apple is brilliant at herding sheeple.
if you succumb to the hype and get the iphone 4 do indeed jailbreak or you're only using 25% of your phones potential, and do not buy the ipod touch its a severely crippled version of the iphone in ways you cant even imagine or will ever see advertised.
but truly the htc evo should get your money, theres even an app to theme the iphone like the htc evo.
