L90 how to change lock screen text AND how to individualize SMS tones?

[magnoliasouth]

I am totally loving this phone, so far. There are just two problems I have and so I have two simple questions:

1. Is there a way to change the lock screen text like you can in Samsung's Galaxy? Surely this phone has a way!

2. How can I individualize SMS tones for my contacts like Samsung's Galaxy S4? Also, surely this phone has a way!
