For anyone like me who's too lazy to upgrade their firmware, but wants to enjoy 2.2.1 apps, here's a fairly simple way to mod them to work on your OS.

Using Winzip and wordpad follow these steps:

Step #1. After you buy your app from itunes, drag it to your desktop.

Step #2. Using winzip, extract the ipa and open (double click) to the application file.

Step #3. Look for the info.plist file, then right click on it.

Step #4. After right clicking, it will say 'open with' then choose word pad.

Step #5. Scroll towards the bottom of the plist file and it should say something like "OS firmware 2.2.1". This is where you change it to say "2.2" by deleting the .1.

Step#6. Click SAVE to save the file.

Step #7. After you're done, open it one more time to check that it saved your changes because I usually have to save it twice.

After you verify it's finished, double click on it and itunes will ask you, "replace file?' and click yes.

Sync and you're done.

Expect crashes from any apps that make calls to a API that isn't available in your firmware.

Maybe for some.. However, I have modded over 19 apps and have seen zero issues. Use at your own risk.

PM me and I can help you.

Didn't work for me either. I tried to mod the plist for a 2.2.1 app to work on 2.2 and it still won't sync.

[NArush]

Make sure to find where it reads:
[key]MinimumOSVersion[/key]
[string]2.2.1[/string].

This is where you alter the file to 2.2 or whatever. This should be near the end of the plist file.

I did get it to work but it seems that free apps arent working if you doubt it use paid apps it works like a charm then

Exactly. I know it is a pain in the butt sometimes but just upgrade.

[soulthoughts]

I think it might be an API thing. I can't get Oregon Trail or Let's Golf to work.

[NArush]

Soulthoughts, I have both of those apps and they work fine for me and have never crashed. PM me and I'd be glad to help ya.

When I attempt this I get the following error (when I double click and try to install the app in iTunes):
The application could not be added to your iTunes library because it is not a valid application.

It appears if I make any changes to an app it apparently changes the signature of the file.
Any ideas?

[NArush]

Which ipa are you modding? Check post #7 too. That's the only area you modify. PM me if you need help.

Hey NArush did you get any luck with NBA Game Time app

I used FWChanger and it worked. I know some people have had issues with FWChanger no problems yet, I'll have to wait and see.
