Today’s tips is aimed at the urban dwellers. Do you frequently notice that your iPhone, iPod touch, or iPad is asking you to join random, unknown networks while you’re walking, riding, or even just sitting at a nearby café? Unless you like these interruptions, there’s an easy way to rid yourself of these annoying notifications. Simply open the Settings app, tap Wi-Fi, and set the “Ask to Join Networks” slider to off. Now your device will only connect to networks that it’s previously connected to—like the ones at your home and work—unless you open that same Wi-Fi menu and manually look for a new connection. It can be a little less handy, but it’s also a lot less aggravating.
