How to remove text previews from the lock screen in the iPhone 4?

So I just got an iPhone 4S, and discovered the most annoying feature to me is the fact that partial texts are shown on the lock screen.
For privacy reasons I do not at all want this. I don't mind being notified that I've gotten a text, but I don't want any portion of that new text to be visible until one enters the pass code.
I've tried playing with all the settings, but thus far nothing has removed this feature.
Please, someone tell me it is possible to get rid of this stupid feature?

Can I connect two Bluetooth devices to my iPhone simultaneously?

I'm currently using an iPhone 5 with a sportzbeatz stereo Bluetooth earphones, (which are great by the way) but I'm considering buying the pebble smart watch.

But say I'd still like to be able to see what song is playing and change it on my wrist, but still have the music being transmitted to my earphones.
Has anyone had any experience with this or know if it will or won't work?
