i need to use my phone in japan, i've rented a sim card but i don't know if it will work with just pwnage or if i need use yellowsn0w or both. Thanks!
If your iPhone is not unlocked, you have to unlock it...
That means using whatever you have to use for your model of phone.
You can find the proper tutorials for each model on the Dev Team's links.
Or just put the SIM in and see if it works...![]()
What's your phone model, what's your computer? Tell us that info and we'll give you easy-to-follow instructions.
iphone 3g 16 gb and im using a macbook pro intel. seriously, thanks so much!
OK, here's what to do, assuming your phone's already on 3.0.1. If it's not, update in iTunes.
If you want to save contacts, texts, etc, back up the phone in iTunes. Then:
1. Follow this tutorial to jailbreak your phone with RedSn0w:

(note, you must use the 3.0 firmware for this stage, NOT the 3.0.1 version.)
2. Follow this tutorial to unlock it with UltraSn0w:

3. Restore from your back up
Sorry I don't get it, I should upgrade to 3.0.1 or I shouldn't? or does that apply to the redsn0w program?
