I’ve been running an unlocked/jailbroken 2G-8Gb on os 3.1.2 forever… Will one of these work to jailbreak my phone again once I upgrade to iOS 4? Will iTunes even let me do that since my phone is a couple generations old?

Thanks in advance for any help!

I don’t think you can upgrade the 2g to osi 4.0

i wouldn’t recommend upgrading to iOS4 on a 2G iPhone it will just make your phone REALLY slow!!

I’m in the same predicament. I’ve given my unlocked/ jailbroken iPhone 2G to my son, and I’m using a new unlocked iTouch instead. [I bought a Sony Ericsson phone.] But the applications I’ve bought keep on getting updated to OS4.0 standards, thus, some games I bought for the iPhone2G don’t work anymore.

No, 3.1.3 for 2G is max. But remain unlocked to any GSM.

I see that the phone must be actvated. Does that mean connected to a phone carrier or so that you can get get to wifi or internet on it? Mine and get to wifi but I did not carrier activate it.
