iphone password unlock

Dear experts,
I have an apple iphone and I forgot its password. I do not think I will be able to recollect it.

What are my choices to get it to factory settings?
As a clarification, this is an iphone purchased in the US and it has been given to my grandmother who lives in India.
Kindly advice.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Manual method
Press and then hold Home button simultaneously with the Sleep/Wake button. Home is found on your iPhone display, while the Sleep/Wake button is located on top of the unit.
Hold the two buttons until your phone turns off to restart. This may take around 30 seconds to a minute.
When you see the Apple logo, it is time to release the buttons.
Wait until the logo disappears.
There will be no options nor there will be any notifications, your iPhone will automatically reset. So be sure that you are really willing to hard-reset your unit before you start the process.
Once your phone is done deleting all files and resetting of your settings, it will reboot on its own.
Wait for a while since your iPhone needs to load.
You are done resetting.
