The codesign script is the key.

You can work around this with a bit of tinkering as follows...

rename /usr/bin/codesign to /usr/bin/codesign.orig

now create a new codesign file and fill with the following perl script

#!/usr/bin/perl 
#
$appDir=$ARGV[$#ARGV];
$appDir=~s/ /\\ /g;
@tmpAry=split(/\//,$appDir);
$baseAppName=$tmpAry[$#tmpAry];
$baseAppName=~s/\.app$//;
$realAppName="$appDir"."/$baseAppName";

$sign=0;
for($b=0;$b<$#ARGV;$b++) {
if($ARGV[$b] eq "-s") {
$sign=1;
}
}

$mums=`file $realAppName`;
if($sign==1 && $mums=~/executable arm/) {
#print "Signing armv6..\n"; 
$dev="/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/";
$tmp="$appDir"."/tmpbin";
`$dev/lipo -create $realAppName -output $tmp`;
`mv $tmp $realAppName`;
system("/usr/bin/codesign.orig",@ARGV);
`$dev/lipo -thin armv6 $realAppName -output $tmp`;
`mv $tmp $realAppName`;
system("rm $appDir"."/CodeResources");
system("cp $appDir"."/_CodeSignature/CodeResources $appDir"."/CodeResources");
exit 0;
} else {
exec '/usr/bin/codesign.orig',@ARGV;
}

set as executable and you should now be able to run 'on device' quite happily

btw; one little trick that got me for a while

See the two lines here

system("rm $appDir"."/CodeResources");
system("cp $appDir"."/_CodeSignature/CodeResources

For some reason the iPhone won't follow the symbolic link to CodeResources so instead we need to copy the location BUT when you actually want to codesign something properly you must comment these two lines out.
ie you want to submit your app to apple for the app store!


ps; please note, I have never tried this on any SDK other than the initial 'final' release, so it might not work with any of the newer versions. Let me know if it does though, then I can upgrade too :P

Trapper: I am new to macs but i have succesfully created and tested my app on the simulator you say to "rename /usr/bin/codesign to /usr/bin/codesign.orig"

How do i do this. Where do i find it? Can you explain this part to me alittle more so i can actually get my app out there?

Your a badass for helping me!

Thanks
