iPhone reboots in Walmart?

Does anyone else's iPhone reboot in WalMart? Mine almost never reboots, but when I'm in WalMart, it will reboot pretty much any time I try to do anything with it. I was thinking that it was maybe the anti-theft scanners they use, but my friend's iPhone doesn't have the same problem.

Maybe it's just trying to make me go to a high class supermarket :)

Yea of course, wallmart have a security system like no other. If you try and steal a box of ceral ninjas are gonna fly out of the sky wielding iphones and then give you the wrath of a freezing and crashing safari until you go crazy enough to give it back. Joking aside, they make cell phone jammers, not cell phone "restarters" doubt its wall mart.. just a one of those things.
 
Ok, that's weird. My iPhone never randomly reboots itself, and I rarely go to walmart, since I F-in' hate that place, but the other day I had to drive my handicapped uncle there, and as we were in the check out, my phone randomly shut down and got stuck at the apple logo while rebooting. I had to do a hard reset to get it to come back up.
 
3G signals don't work inside. The same thing will happen in an Apple store. So the story goes.
 
I was just joking around I got it from Apple store employees. Half of the stores that sell the iPhone don't get full signals. 3G doesn't penetrate walls, or so the story goes.

If you're inside a metal framed or walled building, depending on the thickness of the metal and the size of any gaps within the metal relative to the wavelength of the signal you're interested in, the building may act as a weak Faraday cage that weakens or entirely disrupts service.

Some buildings use indoor repeaters to improve reception, offsetting the dampening effects of the walls. Alternatively, some buildings may be made out of materials that aren't as disruptive to the signal such as wood, drywall and brick.

I go to Walmart all the time, at several different locations and I've never had this happen. Are you doing anything with your Iphone when it reboots or does it just do it randomly?

It seems to happen when I try to do something. Maybe use a data connection? Guess I'm not sure about phone calls. It makes the phone nearly unusable there.

I'm posting this from Walmart and I've had no troubles. I did a couple of searches, went into settings and came on this forum without any problems.
 
That is crazy, I have had this same thing happen to me about 4 or 5 times at the Walmart in Northampton Ma. I figured it has something to do with all the electronics or something in the buidling. I actually think I posted about this before. Pretty strange. I have a gen1 phone
 
I think the most plausible theory mentioned thus-far is the network bit. Try turning your wifi off, and see if it crashes then.

what a silly statement, AT&T sends techs to all apple stores to make sure they get full signal
 
Not silly at all. I got a (@*$ signal in the Apple store in Rockingham Mall. (every time I've been there with my iphone, actually)

Just to add...

This is especially true of reinforced concrete with a lot of Rebarb in it.

Buildings with this are terrible for any type of cell phone or WiFi reception.

This actually happened to me the other day. I was in WalMart (unfortunately) and got a call, halfway through my phone just restarted itself.
 
I was in Wal-Mart today and thougth of this thread.

I took out my phone and saw good signal strength and 3G coverage. I checked my email and followed a link to the web, all worked fine for me. *shrug*
 
It probably rebooted from being around so many pre-payed cell phones and got sick. ;)
