iPhone Security

So I was one of the first in the world to purchase the much anticipated Apple iPhone. Needless to say this is one awesome revolutionary device it still has some things Apple needs to work on.

My main concern about this little device is security. With most Palm or Windows Mobile devices you have the option to have a strong password or have some way of remotely killing the phone if it should be lost or stolen. With the iPhone the only option presented by Apple is a 4 digit pin.

Now you must be thinking to yourself this would mean there are 10,000 possibilities of a pin (assuming any digit can be repeated). That being said after three tries the phone does lock you out for a short period of time (which keeps adding time, 1 min the first time 5 min the second time and so on). My concern however is since this phone has a finger touch screen there is a serious problem. Everytime you slide the unlock arrow and type in your pin number your finger prints are left in the exact same spot which would allow anyone to pick up your phone and know the 4 digits you use to login to your phone just by looking at the screen. So now the number of possiblities would go from 10,000 to 24 (assuming there are 4 different digits).

So now someone could easily "guess" this pin, login to your phone, read your emails, send emails, make calls, steal contact information and so forth. I posted this question recently on an Apple discussion board and for some reason the post was locked and then deleted. Most answers ranged from chill out to there is no personal information on the phone to it is not made for business. Although the phone is not made specificallt for business it still does provide functionality to add a business email account over POP, IMAP or through a VPN connection.

Some users replied that most Palm or mobile devices would have the same issue, but I argue with those devices a stylus can be used and with the iPhone this is not the case.

I wonder if the only two good solutions are to keep the screen very dirty or spotlessly clean......

Anyone?
