Best way to restore & jailbreak/unlock iphone 3gs?
I just bought a used iphone 3gs off of craigslist, and want to restore it to factory defaults before jailbreaking and unlocking it again (and if possible, do so with an untethered jailbreak.
Phone : iphone 3gs
modem firmware: 5.11.07
I was told this is a newer iphone, and has the new boot rom. If i restart the iphone, I'll have to jailbreak the phone.
Is this the best way to go about restoring the phone?
1. restore phone with 3.1.2 firmware in itunes
2. find a person with att sim card, put in iphone, and use spirit to jailbreak. (is it this easy to get past the activation screen?)
3. use blacksn0w to unlock.
Is there a better version I can upgrade to and still come out with an untethered unlocked iphone?
Sorry for all the questions - just need some guidance. I haven't done an unlock and jailbreak since the iphone 2g... so it's been a long while! Please let me know if additional information is needed.
i think you can delete my post. I just read the reply here:
It looks like I hav no choice but to wait for the new firmware to come out, and a safe unlock/jailbreak with untether.
However, now I'm wondering if there's a safe way to reset the iphone to 3.1.2 factory and unlock and jailbreka it again on the new bootrom?
Unfortunately, the only way to completely clean the iPhone is to do an Erase All Content and Settings -- and this also erases the firmware. Without a 3.1.2 SHSH on file with saurik's server or a copy of your SHSH blobs from TinyTSS, you will be unable to re-flash 3.1.2.
As 3.1.3 includes a baseband upgrade that is not yet unlocked, and also requires the Spirit jailbreak (which requires a legit AT&T sim to activate), it is not a good solution for users who need to unlock.
If you don't have the SHSH, best bet is just to wait -- it's not very long now until the new hardware, new jailbreaks, new unlocks, etc. are released.
The preceding forum post has been brought to you by the letter "N" and the number 42.
