My wife and I both have the 8350i. Neither of the phones have the General Settings to choose from listed under th Security Options. I have looked under the Advanced Options and it is now where to be found. The reason I need to reset the Master Radio is when I hook the phones up to download apps from the Blackberry Apps, there is an error message that comes up and says that the radio is turned off and cannot download, but when I check it says the radio is on. Any help would be appreciated.
Make sure that wi-fi is turned off and mobile network is turned on. Check if you can log into web or not. If you can log into web using mobile network connection then you should be able to download apps from bb app world.
