We are facing an unknow issue in Nokia N70 phones in 2G to 3G reselection. When we set network selection mode as DUAL MODE in a Nokia N70, and do the manual network search, no 3G network is shown. But at the same place when we use another phone (any other Brand)all 3G network are shown. But in some areas N70 phone works perfectly and reselect to 3G automatically. (This happen for every N70 or N73 phone that we checked). If you have faced such issue, please help to solve this problem.
