There are times when we need to enable the Airplane Mode in the iPhone such as if we move to areas where there is no signal reception then turning the Airplane Mode ON will surely help in preventing the battery from drying.
Literally, we turn our iPhone into iPod Touch by enabling the Airplane Mode. But it is known by very few people using iPhone that we can use the Airplane Mode and Wifi together in the new iPhone version 2.0.
The feature will be most useful if you are travelling through a plane giving Wifi services to the passengers. However the use of this feature depends only on you. Let me know how many of you knew this thing?
