From version 1.3.0, iLiberty+ starts to use plist to manage the payloads, this makes its much more easier to update a payload whenever needed.

The repo plist is a standard Apple plist file, each dict item describes a payload, here’s the format:

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>payloads</key>
        <array>
                <dict>
                        <key>Id</key>
                        <string>com.zjlotto.iLiberty.FlashBBTo040313</string>
                        <key>Name</key>
                        <string>Reflash baseband to version 04.03.13_G (BL3.9 only)</string>
                        <key>Author</key>
                        <string>George Zhu</string>
                        <key>Version</key>
                        <string>1.1</string>
                        <key>Script</key>
                        <string>http://iLiberty.zjlotto.com/Payloads2/01BL39BasebandTo040313.sh</string>

You may add multiple repo into iLiberty+, each repo occupies one line, they’ll be scanned one by one when you press the Refresh button. The default repo (if you don’t set any repo, the default one will appear) is:

http://iLiberty.zjlotto.com/repo.plist

The best way to maintain a repo plist is to use a script to generate it, this will salvage you from typos, etc. The following is my quick-and-dirty PHP script used to generate the official iLiberty+ repo plist file:
