I agree with RedEye, but word to the wise...so far there is no one repo source that gives you ALL of the features of the LockInfo; hence the trouble some of us had to go through and navigate in order to come up with the tips contained herein. I used repo sources for installing all of the plugins that I consider to be helpful, but for the main host application, LockInfo, I used WinSCP/SSH method.
If using WinSCP/SSH method seems too risky or complicated, an alternative to this method is to use iFile. It has an automatic installer and it works great. Great program to not only navigate your iPhone's internal files! I love it.
So, if you choose to use iFile, simply use AppCake or other tools like it to download the latest LockInfo. After installing LockInfo via this independent method (apart from cydia repo sources), you can practically go to any Cydia repo sources and integrate the plugins of your choice. However, you should choose one repo source for your plugins and be consistent. If you install some from ModMyI while trying to install others from BeYourIphone, you may run into some conflicts. Stick with one! That being said, plugins from David Ashman's repo did not seem to cause any cancellations or conflicts.
