redsn0w 0.9.5 BETA

Reminder: To keep tabs on our no-donation releases, follow our team Twitter account

You can use this redsn0w from June to jailbreak 4.0.2 on iPhone3G and iPod2G(non-MC version). Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you're at 4.0.2).

This will also hacktivate your iPhone3G at 4.0.2 if you haven't already been activated by iTunes. Install ultrasn0w if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

If you've updated to 4.1beta2 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you're at 4.1beta2).

Don't do this if you need the ultrasn0w carrier unlock!!

Note 1: This won't hacktivate your iPhone3G – but for those with legit access to the 4.1beta2 this shouldn't matter. Please don't pirate Apple software

Note 2: If you're at 4.1beta2 you'll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.

Note 3: This is recommended only for power users who can deal with the problems that will pop up as the JB apps fall further behind the beta firmwares.

You can use this redsn0w from June to jailbreak 4.0.1 on iPhone3G. Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you're at 4.0.1).

This will also hacktivate your iPhone3G at 4.0.1 if you haven't already been activated by iTunes. Install ultrasn0w if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

If you've updated to 4.1beta1 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you're at 4.1beta1).

Note 1: This won't hacktivate your iPhone3G – but for those with legit access to the 4.1beta1 this shouldn't matter. Please don't pirate Apple software

Note 2: If you're at 4.1beta1 you'll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.

The latest redsn0w beta should fix any APN or MMS issues that users were seeing. It's safe to re-run it on an already jailbroken iPhone without restoring…just deselect “Install Cydia” if you do that.

The latest redsn0w beta now hacktivates the iPhone3G. It's only for 4.0 final (released on Monday) on iPhone3G and ipt2g (non-MC version).

This is a beta release of redsn0w. It uses the same pwnage2 DFU-mode exploit that we've been using since the 2.x days. Nothing new is revealed to Apple, and it's not applicable to the iPad.

This BETA release supports:

• iPhone 3G and iPod touch 2G only (for now)
• Mac OSX x86 and Windows only (for now)
• the 4.0 official FW only (for now)

If you've already updated your device to 4.0, the next steps are:

1. Make sure you've already activated your iPhone3G or iPod Touch 2G with iTunes (redsn0w won't hacktivate your iPhone3G until Apple's full public release of 4.0)
2. Launch the beta redsn0w 0.9.5b5
3. Select your stock 4.0 ipsw (you've already used this to update your device to 4.0)
4. Select “Install Cydia” and click “Next”. Use DFU mode to install the jailbreak.
5. When your device comes back up, you'll notice Cydia has a blank white icon (we told you many things were broken right now!) Allow Cydia to reorganize, then accept the update it offers. When Cydia restarts, you should see its real logo now.

If you find that you want to back down from the 4.0 until it's more useable, here's how to do it.

1. Restore to official 3.1.2 or 3.1.3. Your baseband won't be downgraded, so you'll get error 1015 at the end of the restore.
2. Use rslite or irecovery to get past error 1015. Using rslite, you'd do:

   % rslite
   rslite v0.2 - by the iPhone Dev Team, 2009.
