Tutorial: How To Use PwnageTool 2.1 and Upgrade iPhone to Firmware 2.1 (Mac)

by Eric Pena on September 15, 2008

From iPhone firmware 2.0.1, I upgraded to 2.1 using iPhone Dev Team’s newly released PwnageTool 2.1 for Mac (Note: If this doesn’t work for you, you can try QuickPwn 1.1 for Mac). As I mentioned in my other post, I didn’t upgrade to 2.0.2 because there wasn’t anything exciting with it. But 2.1 is a different beast, and you must upgrade if you want to have a better relationship with your iPhone, 2G or 3G.

The good news is, if you have already used previous PwnageTools, you should be able to upgrade without difficulty. In fact, I will be refering you to the tutorial I made on how to use PwnageTool 2.0.2, because it’s basically the same way, just replace the files with the new ones.

Follow the PwnageTool tutorial here:


Note: I used iPhone 2G but you can easily follow along if you have an iPhone 3G.

Here’s what you need:

(1) iTunes 8
(2) PwnageTool 2.1 (rapidshare or torrent)
(3) iPhone 2.1 Firmware (2G, 3G) –> So you don’t have to do Step 3 in the tutorial.

Hint: If you have installed Categories from Cydia before, I suggest you delete the apps from the folders you created first or update to the new Categories from Cydia.

Note: When you get to “Step 15. Place your iTunes in Recovery Mode.“, do this instead:

(1) While the iPhone is off, plug it to your Mac.
(2) Hold down the Home and Sleep buttons for about 25 seconds until you see the Steve Jobs cartoon on your iPhone screen. It should now open iTunes.
(3) Continue with Step 16 to 20. That’s it!

What’s great about iPhone 2.1 firmware:

  • Decrease in call set-up failures and dropped calls
  • Significantly better battery life for most users
  • Dramatically reduced time to backup to iTunes
  • Improved email reliability, notably fetching email from POP and Exchange accounts
  • Faster installation of 3rd party applications
  • Fixed bugs causing hangs and crashes for users with lots of third party applications
  • Improved performance in text messaging
  • Faster loading and searching of contacts
  • Improved accuracy of the 3G signal strength display
  • Repeat alert up to two additional times for incoming text messages
  • Option to wipe data after ten failed passcode attempts
  • Genius playlist creation

Note: While 3G reception has improved a lot, 2G reception remains the same since no baseband update was made.
