iPhone 4 in endless reboot

I received my iPhone 4 yesterday and promptly plugged it into my computer to activate it via iTunes. Unfortunately my battery was completely drained so I had to wait for it to charge a bit before I could activate it. Once activated I did a restore to put all of my things on the new phone and used it the remainder of the evening.

Much to my dismay I woke up this morning, turned it on and saw the activation screen telling me to plug it into iTunes. I turned the phone off and then back on and now the phone is in a dreaded reboot sequence. The Apple logo appears for about ten seconds, disappears for about five seconds and starts the whole process over and over again. I've tried holding down the power button, holding down the power and home buttons, etc. all in multiple variations and number of sequences but I can't get out of the reboot nightmare.

I'm going with my wife to get her iPhone reserved at the Apple store a little later today so I guess I'll have them take a look at it while I'm there.

Any ideas that I should try first or is my unit DOA? Also, do you think the Apple store will have an iPhone to replace my defective unit with if they can't get mine working again?

iMac 24" (Early 2007) & MacBook Pro 17" (Late 2007), Mac OS X (10.6.4)

More strangeness...

If I plug it into a USB power adapter (like the one that comes with the iPhone) I can get it to come up to the activation screen telling me to connect to iTunes. The battery shows 100% at this screen, but if I unplug the phone from the USB power adapter it shuts off (or at least I think that's what's happening) right away. I can't get the phone to power on (in any manner) without having it plugged into something.

I only get the endless reboot if I plug it into my MBP it seems.

I'm not sure it is the same issue since you were able to attempt a restore on your phone. I think my issue is battery related since the phone shuts off immediately after unplugging it from a power source. I'm really hoping Apple will replace this for me quickly at the Apple store. It is a nightmare day to attempt this, but I have no choice on the matter.

I'm in the same boat. When I plug it directly into the wall, I can get it to turn on in emergency call mode. Tapping on the i in the lower right corner shows up a message saying "NO IMEI NO ICCID" and I cannot get it to do anything else. The second I unplug it, I can no longer turn it on. Seems like more than a battery issue.

Unfortunately, I cannot even get it into DFU mode. It just goes into endless reboot and completely ignores anything I try to do to it.

Spoke to an Apple tech through AT&T and he had me go through quite a few different ways of getting to a system restore (the usual way of power+home did not work). Finally managed to get iTunes to recognize the phone and started DLing the restore - but had to end the call to head to work. Checked the restore through my roommate and it popped up a 2006 error and said the iPhone could not be restored.

Guess this one is going back. Wonder if I can get AT&T to reactivate my old phone so I can actually have service.

iphone 4 32GB here as well...I get the 2006 error after attempting to sync with iTunes.

my phone worked great for ~ 2 hours yesterday then would not boot at all. resetting did no good.

i have tried every option out there:
- option click install .ispw
- boot in recovery mode
- tried to restore from new user account
- tried to restore from windows machine
- reset the SMC on my MBP


Pretty sure it's a hardware error; nothing but replacing will fix this. Even AppleCare was stumped. Going into the Apple Store tomorrow, will update.
