Ummm that shouldnt be an issue. please let me know if this continues. i would recommend you wipe before installing my first rom. but if you want or have any fears. I dont see a reason you couldnt install your favorite rom and just flash my latest one over it. Im working hard on getting 1.4 out. i have a clean version that is unthemed almost ready to go. it will include the new rosie apk. launch key. and a few other changes. so hopefully ill have that out for you guys soon.
