I own a SE T600.
It has the well known sleep bug: after a couple of hours if someone call
me it doesn't ring.
I've to keep it "on" by making a call from time to time...


On the rear of the phone I found the code 02W49 and R3A.
So it could be good.
But firmware rev is 38 R2A, non R3A.

Could it be one of the first T600 with good hardware but firmware still
not upgraded?

The last firmware rev is 47 R6A.
Could I solve the problem by firmware update?

Thank You!
