After reading some blogs it looks like it will be.

"The standby button is integrated with the lock button on the left. This is by design and not a bug.
The top right button is used as a mute button in your media player."

My thing is if I want to lock my blackberry with the top left, all it did was lock the keyboard using version .484. Didn't password lock it, just locked the keys. I liked the option we have with .419.
I'll stay with .419 till then.
