A few more questions about the samsung Impression?

[Rick]

I have just a few more questions about the samsung impression. First, how do you change the pictures on the lock screen? You know, when you lock it it shows pictures of clouds and flowers. I don't like that, and I was wondering if there was a way to change it. Also, I wanted to know if it was possible to fix the setting for the ring tone sound. The setting that when you don't answer your phone (text or calls) it starts out low then gets louder as you don't answer it. I mainly want to fix this for text sounds because I have a few good text sounds I could do but its too quiet in the beginning. I can't hear it. Please answer as many of these questions as you can. Thanks
