okay so i got my iphone 4 for christmas. when i plugged it into itunes it automatically updated to 4.2.1 ( god knows why) and now i cant jailbreak unthethered ( my iphone dies alott) so i wud have to rejailbreak it every day for it to work. is there any method for an untethered jailbreak? o by the way i dont plan on doing anything drastic with it. i only want it for MYWI. and thats for school ( so all my friends with itouches can get online during class) and if i bring my netbook in the car. all my friends connected to MYWI on my jailbroken iphone 3g but now i cnt get it 
. any untehered jailbreaks out there) im on a windows 7 starter netbook or a windows vista notebook.
