Contacts, Calendar Appointments, Pictures and Photos, SMSes, Notes, songs, podcasts, etc. are the different types of information we store in our mobile phones. Just imagine the pain and frustration if you lose your phone.
Most mobile phone users don't backup their phone data. If you do, you have saved yourself a lot of pain and frustration. A lot of us use the mobile phone only for 2 main purposes. One to receive and make calls and the other to send and receive text messages. Well, the mobile phone is not just for communication purposes.
Let me give you an example :
The number 1 button on your keypad is stated as the VoiceMail key. As the name implies, it is used to access your voice mailbox to listen to your voice messages left by your callers who could not get you. Press and hold the number 1 button will initiate a call to the Voice Mailbox for you to retrieve your voice messages.
However, I have a suggestion for you. How about programming this number 1 button to your most frequently dialed number instead? If you frequently called your boss, why not program his number to this button? And for those who have aged parents at home, why not program their phone to your number? In an emergency, your aged parents only need to press the number 1 button to get you. There are lots of other ways, you can use your mobile phone to make your life easier. Be creative and don't just use it for voice calls and sms.
