Hi my name is O'B I recently got a Samsung InFuse smart phone. I still have my Samsung Captivate.I love android over iPhone. Problem was my Captivate had issues working multiple times. So I used my wife's upgrade for the Infuse.She wants to keep her non smartphone. I now have 2 operating smartphones . One that wi/fi still works which ATt may shut down. The other works fine. Do you have any advice? Is the Infuse much different? Do I need a data plan for both phones even if I don't use 2nd one for dialing? Thanks!
