I recently got home and plugged my iPhone 5S into my computer with a lightning cable I had found a few months ago on the street. The thing looked brand new and like it was in perfect working order, however, when I plugged my iPhone 5S into the computer with it it gave me a warning message on the screen saying "This cable is not supported by this device and may not work correctly" or something like that. Should I avoid using the lightning cable I found? I always like having at least two cables (one to plug into my computer and take on the go and one for my nightstand to plug the phone in at night), but I don't want any damage coming to my new phone.

What do you guys think?
 
You found a cable, are you sure it's not some 3rd party cable?

It very well could be, but why doesn't iOS7 allow third party cables to work anymore?

Also, it seemed to charge the phone despite the warning. Would using it harm my phone?

They don't allow unlicensed third party cables...not just third party cables in general. Your cable is a cheap knock-off (like the ones purportedly sold by Apple on Amazon).
 
Maxboost charger doesn't work with 5S/IOS7

:mad: Yep, got the same issue with IOS7 and my Maxboost that's been great to use with my iPhone5 in mid afternoon when my battery got low. It still works with my 5 and iOS7.

Just got my iPhone 5S/IOS7 and the Maxboost doesn't work!!!! :(

Wow that's terrible, a $70 device not working right.

My $20 battery case from eBay still works and doesn't even display an incompatibility message. iOS7 is too aggressive in it's cable detection to the point where even supposedly 'compatible' accessories display errors.
 
All of my chinese knock off cables give the error, and sometimes they won't charge. All I do is flip the plug around and it charges/syncs.

That's worrisome. The Lightning technology revolves around a chip that manages the variable functionality of the cable and provides for reversible insertion. What you describe is a cable from a manufacturer that didn't make the least effort to provide minimal Lightning functionality. I would be skeptical of what such a cable might do to my expensive phone and computer.
