I'm not sure if there have been other posts about this, but it seems that some people have been having trouble with installing the 2.0 firmware on their iPod touch/iPhones. Keep in mind I will only be providing help for installing the firmware, assuming you already have a copy of the 2.0 firmware. I will not provide links or references as to where you can acquire a copy of it. To install the 2.0 firmware, you must have a copy of both the 1.1.4 and 2.0 firmware. 1. Download the iPod touch/iPhone PwnageTool v1.0 at http://www.iphone-dev.org/ 2. When you have the application running, click "Browse .ipsw". Select the 1.1.4 firmware and allow the application to recognize it. 3. Once it has recognized it, click iPwner and follow the instructions. 4. Now click "Browse .ipsw" again and select the 2.0 firmware. Let it recognize it. 5. Click "IPSW Builder" and let the application create a new custom firmware with the original 2.0. You should probably save it separately from where your original firmware is located. 6. Now you can exit out of the Pwnage Tool. Open iTunes. 7. Put your iPod touch into restore mode (hold power and menu buttons till it restarts and when it does, let go of the power button but keep holding the menu button till the Connect to iTunes shows up). 8. Select the new custom 2.0 firmware you just created (alt/option + Restore). Your iPod touch/iPhone should now have have the 2.0 firmware loaded in it! Congrats. I did this on my MacBook Pro Intel Core2Duo with Leopard 10.5.2, 2gb ram. I'm not sure how similar it is on 10.4 Tiger or on a PC. Please let me know if I have forgotten to include any steps or if you have anything to add. Edit: I have not tried the new 2.0 beta version (build 5A240d) that was just released 4/8/08. Good luck!
