So I went to BB and got the NS4G and am not thrilled with the radio it has. Weak wifi and really poor in house reception called Sprint and they are sending me a Airwave(mini tower) or whatever to hook up in my house for free to keep me as a customer. Well I really want to return the NS4G and get the SGSII the day it launches. The question is how should I handle this? If I assume correctly when I return the phone to BB they will cancel my contract correct? What can I do to return the NS4G and get the SGSII for 2/yr price without ****ing up the Airwave they are sending me?
