BiteYourApple
This repo contains a wide range of apps, mods and ringtones for your iPhone. This is one of those all-in-one repos that holds some highly popular and useful Cydia apps and tweaks. It even contains some new jailbreak tweaks for the iOS 5. Definitely a Cydia source that is worth adding.
Apps to Look Out For: UISettings-iOS5, Springtomize 2, SMS+, iBlacklist, iFile, Infiniboard, Infinidock, Infinifolders, Graviboard, GravityLockScreen, Dreamboard
P0dulo
Not a very well-known repository but once you browse the content of this repo, you will find that it contains a wide range of pretty much anything. Apps, tweaks, utilities, addons, themes, ringtones, emulators, you name it. The number of content is not that high but it makes up for the quality.
Apps to Look Out For: Auto3G, Barrel, Graviboard, Gridlock, Infinidock, Infinifolders, Move LockScreen to Unlock, RetinaPad, Multifl0w
HackYouriPhone
Now the contents of this particular repo is ridiculously huge, it is almost overwhelming. The usual roundup of apps, tweaks, ringtones, themes, mods are here along with IPAs and even DLC (downloadable content) for App Store apps. Some of the entries are in Italian but they're not that prevalent. Another must-have repository.
Apps to Look Out For: BBSettings, BeyondSMS, biteSMS, CallBar, CleverPin, FolderLock, FoldersInFolders, Infiniboard, Infinidock, RetinaPad
iCauseFX
Another repository that is rich in content. One thing that you will notice about this Cydia source is the wealthy selection of themes although there is no shortage of apps and tweaks to be found in here. We recommend that you install the iCauseFx repo icons after adding this source for easier package browsing.
Apps to Look Out For: Barrel 2, BBSettings, 3G Unrestrictor, UISettings, AdBlock, Insomnia Pro, Lockdown Pro, LockInfo
iHacks
iHacks is yet another repo that has pretty much anything. Apps, tweaks, HD themes, utilities, ringtones and even themes for SBSettings. It also features some unlockable DLCs and hacks for App Store games. Another essential repo that any jailbreak enthusiast should have.
Apps to Look Out For: Applocker, AndroidLock XT, biteSMS, RetinaPad, FaceBreak, SleepFX, SMS+, Springtomize 2, WeeSearch Pro for Notification Center, Infiniboard, Infinidock, Inifinifolders
PwnCenter
When it comes to ringtones, themes and wallpaper, then you can't go wrong with this source. This repo specializes in hosting multimedia content rather than the usual apps and tweaks. Again this repo hardly has any tweak or app, so if those are what you are looking for, then you might want to look elsewhere.
Apps to Look Out For: FiveDockRows, Fix Safari Cookies, not many notable apps here but you will find tons of themes, ringtones and wallpaper.
