A friend of mine was sold an sgs by o2 this week without a data plan. This was at her request because she is not that tech savvy and did not appreciate how integral to android data is. l pointed out that unless she got a data plan she needed to turn off mobile internet to avoid getting stung but when I tried there did not appear to be any way to do it.the options that I have in the settings and power button menu on my desire were missing. I thought these settings were stock android. Am I wrong? Or have samsung or o2 removed these settings?
