i dont see a problem with this.

same goes for a lot of other phones, so what?

on my samsung jet i have 3 ways to unlock the phone once locked:
- hold the lock-key until phone unlocks
- push any key to activate the screen and touch the lock-button until the phone unlocks
- push any key to activate the screen and draw gesture to unluck

and i dont even have a favorite way to unlock it. i always use another way to do it.
