Tutorial on how I Jailbroke my iPhone, my favorite applications, sources and themes. Also theme fixes.
My thoughts on Jailbreaking my iPhone 4S:
Pros:
1.) Custom visual graphics: Icon customization, Custom Lock screen information, etc.
2.) More system customization, hiding icons, and easier accessibility.
3.) Possibility to get 'pay' applications for free.
Cons:
1.) I've noticed that my iPhone has been slighly laggy on occassion. This is rare, but does happen.
