just tried sapphire for the first time.  i think it was the smoothest install i've ever had, smoother than official 2.1, leaked 2.2, and even SS44 (which is still a very nice rom!).  
the default kernel only has slots for 125 and 400, when i usually ran at 250 for a min.  what do you guys prefer?
does anyone know if the nfl mobile app requires 3g signal?  i get no signal where i live, but it will not load on wifi.  i did not get the error about needing verizon though, it just sits there blinking loading.  
that was the only issue i had, and it may not even be a sapphire thing.  every other app loaded great, and so far my camera seems to be a lot snappier than it was in either the leaked frf84b or Ss44.
