If you have already seen my how to jailbreak, than this is stuff you need to know. Sources, apps, tweaks, sites, and mods are all on this and cramed into one instructable! go on to step one to learn about sources ands sites
Step 1: Sources and sites
This first step is for all you need to know about the sources. Sources are what you use for tweaks, mods, and apps. Most tweaks are free and require you to install more tweaks while others cost money. You might want to know my recommendations. One is winter board. It can help you with your spring board- aka home menu. You can remove the bottom silver thing. or you can instal a android lock. It can also make backgrounds. On winter board, I recommend HTC lock screen. It looks just like a HTC.
Winterboard is free and donsen't require you to enter just boot mode. Another one is barrel. It makes your spring board slide diffrent. It can curl it up when you slide to a diffrent spring board. Now that you know Sources, move on to apps.
A site is a url to add source. Some sources require sites. One example of a site is iphonerepo. Another is insanelyrepo. I don't recommend adding them because it may be illegal or might spam cydia. I really don't have any good site or source.
Basicly, a source comes from a site.
