How can solve wifi problem in blackberry tour 2 ?

Once I also faced this problem and at that I was not able to understand what was happening. I consulted the technician of the company and he told me that you can only replace the model because repairing will cost you more than a new phone. So i think you should buy a new model. So you should go for black berry bold 9650. It has got the all features like 512MB memory and WCDMA, GPRS, 3.2 megapixel camera, LCD display but only the change that you fell here is with its price and the operators with U.S cellular who provide a great customer satisfaction and for this you will have to pay $ 499. If you want another brand then HTC Hero(Sprint): Its price starts from $ 0.01 to $134 and it is the most featured Google android mobile phone and got really some of the special features like smart phone, CDMA technology, internal antenna, trackball for phone navigation, voice recorder, speaker phone, Bluetooth 2.1, Googleandroid OS, 5 megapixel camera, LCD display, which makes it not only the bestGoogle android from the HTC .
