hello all. my issue is this. i live in a area with poor signal. extremely poor actually. in my bedroom while im in bed, ill b lucky to get 2 bars. in class, i usually lose signal all together. which in turn sucks more battery as its always searching 4 a signal. do you think a different radio would make a difference? a friend in my class is on the same provider with his sa,sung galaxy s 2 and gets 3 bars in class..while i cannot even connect to the network. is it possible thi is a hardware issue?
