I recently upgraded the OS to 4.5. Everything was working great until I realized that I don't have the preloaded wallpapers anymore. So, I found out that it was because I didn't use the OS that was specifically for Alltel. I searched every where and finally found the one that I needed. I waited for it to install and everything, but still no preloaded wallpapers! Is there ANY way that I can get these back?

Also, I've noticed that it takes longer for the screen to light up when I want to look at something. It didn't start doing this until I upgraded, so I don't know if that's the problem or not.

Oh, and I have a Micro SD card to save my camera images to. However, it will randomly start saving it on the device for no reason. Anyone know why?
