So you may have seen some of my screenshots from my iPhone about some jailbreak applications that I am using.  I have an iPhone 3GS right now, which is not as capable of handling many of the themes from Cydia as the iPhone 4 is, but I still have my favorites.

Right now, those consist of:

1.  LockInfo

2.  ToneFXs

3.  Winterboard

4.  BytaFont

5.  MusicBar Extended

What are some of you favorites?
