What are some neat tricks I can do with my iPhone?

I just got an iPhone 4. I really like it, but I feel like I'm missing out on a lot of things that it can do. My friends talk about this and that which they do with their phones, but when I ask them how to do it, they just laugh and act like I'm crazy. I'm not crazy, or stupid, I've just never had an iPhone before or any other Apple product. I would really like to be able to use my phone for all the cool things that it can do so can you help me? What are some cool things I can do with my iPhone that are a little out of the norm?

The iPhone has a lot of hidden eggs associated with it. You will have a great time with it once you get a hang of its functionalities.

One of the "cooler" features has to do with the LED lights on the phone. Most people tend to overlook this fact and never come across it.

The idea is to get silent notifications on your phone through your LED lights. Whenever, you get a call or message, you will see the LED light blink or change into another color. This can be set through the settings and is ideal for people looking to get a little bit of extra from their phone.

  • What was the last neat gadget you bought? Ya ya that's nice. I hope it makes you lose weight. Eh herm… I just bought the Kangaroo PC! I love this thing! It's a Windows 10 desktop computer about the size of an iPhone. What's so neat about it? I can use it as a standalone home entertainment system instead of using a Roku, Apple TV or Fire TV… And since it's windows, YOU CAN BROWSE THE WEB AND WATCH ANY ONLINE VIDEOS. Roku, Apple TV and Fire TV don't have web browsers. And the Kangaroo PC is only $99.
