Eris is small, thin, and light - and is a perfect fit for me. This one is rooted (by a friend) and KaosFroyo v.34 has it working brilliantly. I've never been happier with a smartphone. HOWEVER: There's v.35 and v.36, and of course more to come. And, there are other ROMs. I would like to experiment, but not at the expense of reconfiguring everything. Is there a simple, step-by-step procedure for installing and testing other ROMs without killing my setup?
