Hi there, its the first time I comment on this thing. I live in Kerman and ever since they started the 800mhz upgrade, my area has almost turned into a dead zone. Luckily today I found out that the optimization process is at 93%. Ever since the optimization process started, my data connection has dropped and become useless. Even though the 3G sign appears, signal check says there is no data connection. Can't wait until it's completed!
