I recently tried to do the manual 2.2 update...everything went fine, but as we all know, my sirius/xm app went into an infinite loop. So after a very unsuccessful attempt at rooting to fix the problem, I ended up back on 2.0.1 os. This is all well and good b/c I got my xm back, but I want to be running 2.1 or 2.2 (as long as that loop issue has been resolved). Ive looked all over the internet and cant find a working link for the unrooted 2.1 sbf file, anyone know where I can get it? Or do I even need it to receive an OTA of 2.2 when it finally gets to me?
