Just got my S4 and before I had a Jailbroken iPhone 5, I'm wondering if there's a way to do some things like I used to on the iPhone. 1) How do I add widgets to my lockscreen? - all I have is my music when my headphones are in 2) When I get a text message, it shows up as "Message" on my screen. Is there a way to see who sent it? Like show the contact name instead of "Message"
