Hi, With Android 2.2, I only see an item to turn on/off wi-fi, or flight-mode (which turns off all wireless services). But I would like to do the following as well: 1. On the Galaxy Tab, I want to turn on or off the tab's cellular data service. How can I do that? (reason: when I am at home, I do not want to accidentally use my small data plan. The Tab sometimes has trouble connecting to the wi-fi and automatically connects to data service) 2. How can I turn off voice service without using the flight-mode? (My tab is the European version so that it has regular phone functionality). Even if you are using the American version, you can still answer this question if you have a regular Android phone: That is, my question is: how do you turn off voice service but leaving other wireless connections on. This should be possible because I could do it on my old Windows Mobile 6 phone.
