Does anyone know if the attenna has moved on the 8900? My building is marvelous at blocking my cell reception, my 8320 & 8900 were both sitting at one bar of signal. The thing I've noticed is that the 8320 was able to hold onto that bar a lot more consistently. Usally if I'm holding the 8900 is when I'll lose the signal completely, just wondering if something moved or what not.
