Note:
Format phone :
Restores phone to as if it was out of the box. Retains firmware version and operator Variant changes but wipes all applications you have installed. Does not format the memory card so any apps on there may reinstall once powered back up again.

Another way to format some symbian phones :
Power off phone. Press and hold Green, * and 3 and keep them held whilst powering on and for a few seconds after.
Factory Reset :
Resets all settings to defaults but keeps any applications you have installed and photos etc. Both need the Security code, which, by default, is 12345.

========================================
Protecting Mobilephone From Viruses
1. Switch to Bluetooth hidden mode.
If your phone has Bluetooth capability, ensure that the Bluetooth capability is switched to “hidden” or “invisible” mode unless you specifically need it to be visible. This will help prevent other Bluetooth-enabled devices from finding your phone (unless you grant them the necessary permission) and will therefore help protect your phone from worms that spread using the Bluetooth wireless technology.
2. Exercise caution before opening attachments.
When accepting applications sent via Bluetooth, or opening MMS attachments, exercise caution, just as you would when opening an email attachment on your PC, because they may include harmful software. Ensure the application or attachment comes from a known source, and be wary of opening files that have unfamiliar text attached to them, even if they come from someone you know.
3. Only download content from a trusted source.
Trusted sources may include operator portals[2] and other well-known brands that offer adequate protection against viruses and other harmful software. Be aware though that, as with emails, malicious or fraudulent users may be able to fake the appearance of a trusted source.
4. Consider anti-virus software.
Some software is available to prevent phone viruses. You may wish to consider downloading this software.
5. Contact your phone manufacturer if concerned.
If you think you have a virus, call the phone manufacturer’s care line. They can assist you confirm if it is a virus, and help fix the problem.

Mobilephone Maintenance
Charged
Ensure your battery is fully charged, and then completely run it down before recharging. Recharging too early causes your battery to run out of power more quickly.
Secure
For security reasons, enable the PIN on your SIM Card and Phone-lock on your phone to avoid unauthorised used. These security checks will also be activated when the phone is power cycled. You can check with your carrier or the phone manual for the features and also for information on blocking your SIM card and phone IMEI number if the phone is stolen.

Protected
Make sure you use a keypad lock to lock your phone. Unplanned calls can cost a fortune and even though your phone may be in a safe place, such as in a bag, your phone will still get knocked around to a surprising degree. Rough treatment can damage electronic circuit boards so avoid dropping or unnecessarily shaking your phone.

Battery
Be safe with your batteries. Use only genuine batteries from your phone manufacturer and only buy from authorised dealers. Going for the cheap option of a counterfeit battery can be dangerous.

Clean
Don't use harsh detergents, cleaning solvents or harsh chemicals to clean your phone. Wipe only with a soft cloth.

Covered
a protective cover will help repel dust and dirt, and prevent scratches. Make sure the cover you choose is of good quality. Low quality covers with no air pockets can damage you phone by creating humidity inside the cover.

Storing your phone
Always store your phone in a dry place. Avoid rain, high humidity and liquids. All of these may contain minerals that could corrode the electronic circuits.

At the right temperature
To ensure a long life, keep your phone in a stable temperature. Avoid exposing your phone to liquid and/or exposing your phone to extreme temperature change from hot to cold and vice versa. This might create condensation and damage the phone.
