    1. Is a untethered 4.0 Jailbreak for an iPhone 3G out yet? I just need to know if it is, because I was looking to update. I also read how people were having slow phones because they had the multitasking enabled.

    2. Is it possible to unlock an iPhone 3GS[No sim card] that's already on 4.0? My friend wants me to do that for his so that he can use his phone via T-Mobile.


    Thank you so much in advance.

    1. Yes. Use redsn0w. Though multitasking and wallpaper do slow down the phone and pull on the battery. Pro-tip - don't install a back-up from iTunes and start with a fresh iOS4 for best results.

    2. If he has a 3GS with the old bootrom then he can jailbreak iOS4 with redsn0w and unlock with yellowultrasn0w. 3GS on iOS4 with the new bootrom cannot be jailbroken yet and so consequently cannot be unlocked.

    yellowsn0w should be ultrasn0w.

    Damn, what I meant was, is a TETHERED version out. I don't exactly want to go through all the motions of an untethered version.

    What the hell? Why WOULDN'T you want an untethered version? And either way, the only way to jailbreak is with redsn0w which is untethered.
