Where do you see if the iphone has a date code greater than 40? Does this apply to all or just 3G and 3GS?

[LVCIFER]

Just the 3G[s].

Go to Settings>General>About. Look at your "Serial Number". Ofthe 4th and 5th digits (last 2 #s before the letters start) are LOWER than 40, you can have a standard jailbreak. If they're GREATER than 40, you'll have a tethered jailbreak.

October 09 is when it became a standard. If you got your phone before than you should be allright. If your wondering on if you will have a tethered jailbreak or not. I know I got my phone in September and I'm in the NON-tethered jailbreak class.

So there won't be anything on the box or on the outside? So if I buy a 3G it's safe, I can do an un-tethered jb on it no matter what the date?

[LVCIFER]

Correct. But the 3G[s] is OH so much faster and better....

[mcp2]

You're really tempting me to get a 3GS over a 3G. Quick q, does updating the firmware after I've unlocked the phone cause it to be locked again?

[LVCIFER]

Yes it does. The rule of thumb is that whenever Apple releases a new firmware, DO NOT UPDATE. Go to iTunes, and JUST SAY NO when it asks you to update your OS/Firmware. Wait the 2-3 weeks for the jailbreak and unlock to be released. THEN update, jailbreak and unlock your iPhone. It's a pain in the ***, but it's well worth it to be able to keep the privelage of jailbreaking and unlocking.

Interesting thanks, so is there no way to see the date code from the box?

[sargd66]

Isn't the serial number on the box?

[mcp2]

^^That's what I'd like to know! If I buy from the Apple store, it's more than likely going to be new stock isn't it?

[MustangLife]

Yeh you definately want a 3GS. Double ram and processor than 3G.

Isn't the serial number on the box?

Yes, it's on the back of the box.
