Running around the internet, found this, and I thought I would share this to you guys
I have seen too many app now required too high iOS (4.1 , 4.2) when you only need iOS 4.0!
This thread was made based on Windows and using Window's tool, MAC OS user can do the same with the same tool
STEP 1:
Have Winzip or WinRAR and plist editor for Windows
STEP 2:
Go to the .ipa file you want to change iOS version => Open with => Winzip
STEP 3:
Go to Payload => appname.app => find for Info.plist => Right click, choose Open with => plist Editor for Windows
STEP 4:
Find for MinimumOSversion, change to the iOS you want (May not work if it's too low!!)
STEP 5:
Save and close plist editor. If Winzip ask you to update the ipa, choose YES
STEP 6:
Sync file ipa you just edited :thumbsup:
ATTENTION!! :angry:
NOTE!!
This may not work if you changed the MinimumOSversion too low!! Work depend on games!!!
