First introduced in 2007, Apple's iPhone offers many features that other phones do not. But even with these additional features, owners of the iPhone are always looking for additional features and ways of using their devices. There are also several features that the manufacturer and providers would prefer the users not access. In this regard, many private developers and iPhone "experts" have come up with their own iPhone hacks and tricks to further add to the features of the phone and access ones that are not explained. A hack is generally defined as an innovation that customizes a piece of equipment such as the iPhone. Some of the more common iPhone hacks are techniques that enable the phone to have Gmail pushed to the phone, ways to enable tethering before the feature is offered, programs to add additional icons, and also there is a hack that solves the issue some have with the screen flipping when one tries to read it when in a reclining position. These hacks are generally added to the iPhone by way of a download or special coding. Because this involves actually accessing the programming of the phone, one needs to be sure that this hack is from a credible source as many will use iPhone hacks and tricks to do damage to one's device. Because there are so many features included in the iPhone, it can be nearly impossible for the average user to learn everything and even hard to remember it all. There are many helpful tricks that one can obtain from various websites on the internet. A trick on the iPhone is a bit safer due to the fact there is generally no additional coding to add to the phone, it is simply a matter of finding out how to do something and remembering it. The coding and programming is already part of the iPhone, so of the two, iPhone hacks and tricks, tricks are generally safer. Some of the more common tricks that one may find valuable when using their iPhone are making a screen shot by holding the "home" button and then pressing the "power/sleep" button. The screen will then flash and the current screen will be saved in the camera roll. Another tip is in regards to the sound of the ringtone. Generally using a custom ringtone rather than one of the ringtones that are preprogrammed will enable it to be louder. There is also a simple trick to force quit an application by simply pressing the "home" button for six seconds. By using these few iPhone hacks and tricks one can accomplish many additional features with their phone.
