change iphone app "MinimumOSVersion" without xcode

I have a custom app I have to test run.. But it doesnt work on my verizon i开发者_运维百科phone because in the info.plist file MinimumOSVersion is 4.3 when the verizon iphone goes up to 4.2.7.

Is there a way to edit this without xCode so I can use the app? I try to edit it then it wont let me add it into itunes. I have a pc and am using a plist editor to view the plist file in the .ipa file. THANKS!

I think when you are specifying deploy target something more then just a restriction for smaller versions is created. Something is changing in compilation process. So just changing a deploy target without rebuilding your app can cause troubles.
