how can i factory unlock my iPhone 3gs bought from Orange Switzerland!

Only the carrier that the phone is locked to is authorized to unlock it.

So you will need to contact Orange.

"Factory unlocked" would mean it came from the factory without ever having been locked at all. If the phone you have is locked to Orange, you'll need to call them and see if they will unlock it for you.

In Settings > Info > General you will find the IMEI no. of the device.

Many carriers provide an online service by entering the IMEI-no. on their homepage.

Just try your luck, otherwise you have to contact the carrier directly.

Thanks. will try contacting orange

You're welcome.  Good luck.

If Orange contacted you they usually say to wait 24 hours before trying to unlock the phone. Did you wait 24 hours?

Then you need to have a SIM in the phone and Restore it in iTunes as a NEW phone, NOT from a backup. You should get a message saying, "Congratulations, your iPhone is now unlocked."

This is a summary and guide of process

Have you tried it on a different computer?

If this 3GS was previously jailbroken to unlock it then the baseband chip may have been permanently altered and you will not be able to activate that phone.
