Question about charging iPhone 3G S

[SHEDGES]

Quick question, I just purchased a 3G S and so far it is a great device. It's not quite the email machine that my Curve was but the other million features it has more than makes up for it.

For my first charge, I powered off the phone and then plugged it in. A few minutes later I started receiving text messages. It's almost as if it powered back on once I plugged it in. Is this normal? If so, should I just leave it on when I get ready to charge it? Will leaving it on while charging inflict any long-term damage?

Thanks in advance for your help!!

Turning the screen off (tapping the button at the top once) doesn't actually turn the iPhone off...just puts it to sleep. Perfectly safe for it to be on while it's charging. I even take calls while it's in the cradle.

I sometimes go for weeks without shutting down my phone. My 3G is almost a year old with no problems.

I never turn the phone off, it takes a long time and I find it wastes battery power to turn off and on especially while jailbroken

Yes, if you plug in the iPhone when it's off, it automatically turns back on. There is nothing wrong with charging the phone while it's on.
