Draining iPhone battery requires iTunes activation?

[GianlucaM]

I did a search and could not find this subject.

Yesterday while I was out my iPhone 3G battery drained completely until the phone shut itself off.
Fine no problem there, we all know the battery life sucks.
I got back home and recharged it and when it had enough power I went to turn it on and it flashed at me that it wanted to be connected to iTunes and would only allow emergency calls until then.
So I had to connect it to iTunes and the iPhone displayed a message that said that it was "now activated".
WTF?
What if I had been travelling without my PC and the battery had drained?
Is this a known bug?

Thanks,

My phone randomly says "Now Activated" from doing resets, although I'm not sure about the first part.
I'm guessing it fully drained from it's auto-off @ 5% mark and lost some required information, which is why you needed it to sync.
It shouldn't have 100% drained from being left alone for a day though, unless you were playing music or something

#####ing session starts here.
I was playing music when it turned off because the battery was drained, but there's no excuse for "a phone" to become non functional because the battery's dead (even after recharging it).
I love my iPhone as a toy but as professional tool it sucks.
Apple should strip the letters "phone" and only call it "i".
Apple should take a lesson from people like Nokia and learn how to make a phone that does not drop calls, does not die when the battery runs out and does not prevent you from dialing a number because it's busy downloading email.
