wifi + charging = warm?

[riftweaver]

I had an active wifi connection for a half-hour this morning, copying files via ssh to my iPhone. (1.1.3, jailbroken, disabled auto-lock for the duration.)

The phone was plugged into the dock to stay charged while I copied files. When I pulled the phone off the dock afterwards, I was surprised that the phone was so warm to the touch. It seemed the screen was warmer than the back.

Is this normal?

I confess I've been concerned about running warm, ever since I recently charged my phone with an old iPod (12v) brick/firewire, and the phone got extremely warm. I'm looking for reassurance that what I describe above is expected behavior.

Thanks!

Yes, for what you were doing this is normal behavior for the iPhone.

yes. Mine does the same thing when left on for long periods of time
