I have my Razr MAXX HD with 4.1.1 (System 9.1.41.XT926.Verizon.en.US) after using the IPhone for some years. On the IPhone you were able to select a parameter that said when Wi-Fi was available, use this as the referred method for sending and receiving data. Now that I don't have unlimited data anymore (no thanks to Verizon) it is more critical to use Wi-Fi for data usage. Is there a setting on the Droid to choose this option? Or am I to presume that when I have a Wi-Fi connection that all data will be sent/received over the Wi-Fi and not over the Mobile Network?
