I didn't notice much difference from GB to ICS, but I didn't stay on stock ICS for very long either. I flashed the latest leaked FH13 modem yesterday and I've noticed quite a bit of improvement, although I did get LOS once, whereas I hadn't experienced it before.
Btw I don't get 4G anywhere around here so I'm just going by 3G and phone signal.

mind if i ask how you did this or do you have a link by any chance? i really liked ICS but couldn't use it because of poor reception and internet. i briefly remember seeing something about flashing the modem but couldn't find anything usefull. did you use ODIN to do this?
Sprint agreed to send me new phone....actually had great customer service from them! The sprint store people on the other hand...f$@&ing morons!
