Hey dudes. This was easier than I thought it would be. Go to /system/app/Rosie.apk, and dload it to your comp (I just emailed it to myself using Android Mate). Rename it to Rosie.zip. Inside are all the images, and even .xml files that control layout and stuff. I figure just edit these images, repack the .apk and push it to the phone. A bit new to this, so how exactly would you overwrite the old Rosie.apk? Thanks I'll be posting updates once I start editing the GUI.
