So I have bought a BEHOLD II off Ebay ,and I'm still wait for it to ship to my house. I'm wondering if somehow I could turn off 3g network since I don't have the plan , and I only want to use it by WIFI . Here is a quote from BHold II manual "When you are not in range of a Wi-Fi connection, your normal cellular network takes over and keeps you connected. Your phone switches automatically from Wi-Fi to cellular whenever it's necessary to maintain your connection, whether your phone is displaying the Home screen or in the middle of an active call. The switching process is virtually unnoticeable." That means if I don't have 3g plan rightnow on my Behold II , then I don't have 3g network on my phone obviously right . I only want use WIFI because that is what I want, but what happen if the 3G network turn on when I am in 3G network area , and Tmobile will charge me the date plan for using it . My questions are : is there anyway to turn off 3g network from Behold 2 ? and if I don't have 3g plan , can I still use WIFI constantly on the Behold II without 3G , and do tmobile charge me even if I don't have the plan ? Another quick question : How to update the BUG FIX for Behold II , Do we go to setting and click update.We do need the internet connection in order to get the update over-the-air from Tmobile right ? Thanks for all of your answer .
