Im using my 9530 storm on ATT. Ive read around on one of the BB forums that some people have installed the 9500 OS on a 9530 (not sure if its true, poster may have been confused). Since Im only using the GSM portion would it be better for me to us a GSM only OS? Will this even work? I have a feeling its not even possible but I figured it cant hurt to ask. Thanks for your input.
