1. 新建一个目录 $appname
2. 新建文件夹 Payload和文件iTunesArtwork (注意大小写,iTunesArtwork由图标文件改名得到)
3. 包XXX.app文件夹内容放到Payload下，我一般连上真机，winscp下载 (/var/mobile/applications下)
4. 修改XXX.app下的Info.plist，现在的Info.plist一般都是二进制文件了。可以用专门的工具(叫做pledit)修改。其实自己建一个文本格式的文件也能正常工作。格式见附录。
5. 将$appname里的内容，用winrar压缩，选择zip格式，后缀名直接改为.ipa即可。
6. 可以用iTunes同步到真机了。注意真机必须做一下同步非appstore ipa的破解。
附：Info.plist格式

别的不太重要，粗体部分的是<key>SignerIdentity</key>
<string>Apple iPhone OS Application Signing</string>必须的。
