you know what,
my brand new atrix shows only 2-3 signal bars and its still holds on to calls and all but my 3 yrs old nokia e51 gets full signal and has better voice quality.
height is on 3g of docomo,nokia is just 3.6mbps hsdpa and atrix as you know is 14.4 mbps.
now i dont know whether its docomo who is up to mischief but speedtests are locked on 500 kbps and nokia gives far better throughout .
I am not able to explain this.'I blame docomo as i think they might have capped network speed.
