Apple released an update to the iPhone OS today. The 3.1 iPhone update brings lots of little improvements. Don’t let iTunes tempt you with them if you have an unlocked iPhone. The new firmware will upgrade your baseband firmware, relocking your iPhone and, potentially, making it impossible to unlock again.
The good news is that your iPhone can still have that 3.1 iPhonee goodness and your unlocked iPhone. You just need to trust in the iPhone Dev team, because their tools provide a way to install the update without updating the baseband and breaking the unlock.
If you update to Apple’s new software using the normal iTunes process, you will lose your ultrasn0w unlock. In fact you may lose it permanently, because for most people the baseband firmware cannot be reverted to a previous version (unlike the main application CPU firmware).
But don’t worry…our PwnageTool program lets you update your main firmware without touching your baseband firmware, so you can still have the best of both worlds. But you must be diligent about saying “no” to your iTunes request this week to update your firmware.
As always, eliminate the middle-men and get the PwnageTool and all your iPhone accessories direct from the source.
For those who missed it, you can jailbreak iPhones running the 3.0.1 firmware using RedSn0w.
“You can re-use redsn0w v0.8 we released a few weeks ago to jailbreak today’s 3.0.1 update. Just let iTunes update or restore you to official 3.0.1 then run redsn0w. The only “trick” is that when redsn0w asks you to identify the IPSW used, point it at the 3.0 IPSW instead of the 3.0.1 one. After the jailbreak, reinstall ultrasn0w 0.9 if you need the unlock.”

Yes, the iPhone Dev Team is just that awesome. They’ve released updates to RedSnow, their easy jailbreaking tool, and UltraSn0w, their iPhone 3G and now 3GS unlocking tool.
With this combo, you can jailbreak your iPhone to run unofficial 3rd party applications with RedSn0w (thats RedSn0w, with a zero). Then you can use one of those unofficial 3rd party applications called UltraSn0w (again, with a zero) to unlock your phone so you can use it with a 3rd party GSM carrier.
Note: Don’t go rushing to install the 3.1 firmware that is in beta now. Baseband upgrades can break your unlock and may make it impossible to ever unlock again.
If you have an unlocked iPhone 3G you can now take advantage of the new 3.0 firmware! First, use RedSn0w (that’s a zero in there, not an ‘o’, to jailbreak your phone, then use UltraSn0w to unlock it! For more info on UltraSn0w, go to the source. This apparently supersedes the original YellowSn0w unlock for the 3G.
Note, this doesn’t work with the 3.1 firmware betas that are being circulated, at least not yet.
Redsnow is a sort of a jailbreaking and unlocking swiss-army knife for older iPhones.
Redsn0w is an easy to use, multi-platform, multi-device jailbreaking and unlocking (iPhone 2G only) tool for theiPhone 2G (original iPhone), the iPhone 3G (but not the 3GS) and also the iPod touch (first and second generation). Currently it is available for Windows and Mac OS X
Please note this will not unlock the iPhone 3G or 3GS. If you have an unlocked iPhone 3G, don’t use this until you’ve obtained an updated version of the YellowSn0w unlock.
