Please note that RedSn0w is still in beta. If you are not an iPhone developer or jailbreak developer, it’s probably better to hold off. Also, if you rely on a carrier unlock, know that you should not update. You must also be a registered iOS developer in order to obtain the iOS 5 beta.
iOS 5 is only compatible with the following devices:
- iPod touch 3G
- iPod touch 4G
- iPad 1
- iPhone4 (GSM)
- iPhone4 (CDMA)
1) Download the iOS 5 beta. Again, you must be a registered Apple developer in order to obtain this. We don’t encourage downloading through another means as we are sure Apple can see when users connect whether or not an Apple ID is tied to a developer account or not.
2) With the iTunes 10.5 Beta, update or restore your device to iOS 5 as if you were doing a regular firmware update. You should now have the iOS 5 beta on your iPhone, iPod touch or iPad.
3) Download redsn0w from the Dev-Team (link to dev-team blog, not a direct download)
4) Launch redsn0w and point it to your latest firmware.
5) Let redsn0w find your current firmware.
6) Hit next.
7) Check off the install Cydia option and then click next.
8) Follow the onscreen directions: have your device plugged in, but powered off. From there you will be told to put your phone into DFU mode. the prompts onscreen will show you exactly how to do so.
9) Al you can do now is wait for redsn0w to work its magic.
10) You now have a jailbroken iPhone. Note, this is a tethered jb. You must physically plug your iDevice into your computer via USB every time you have to reboot.
