So I've made a couple of observations that some may find curious or may not care about at all, that have lead me to some questions I'm hoping some one might be able to answer.
If you go into settings/date and time the first option is a check box that says Automatic (use network-provided values). If you uncheck that it does not stick through a reboot. Upon restarting your phone this box will be checked once again.
Now for the interesting part. If I put the phone into flight mode, uncheck the automatic box and then change the time and/or date. The instant I re-check automatic the time is reset correctly. How is this possible? I thought that flight mode actually turned the radio off. If it does indeed turn the radio off then how is the phone able to instantly set the time to the correct value?
