I see that this will work with the iPhone 4S but will it also work with the iPhone 4?

Yes it fits both. My husband has the iPhone 4 and I have the iPhone 4S and we share each have one.

It won't work. The iPhone 4 charge port is very different from the iPhone 4s. I would recommend looking for a 4s charge port.

Yes, it works very well with my IPhone 4S, I did not have any problem so far. Great pics!

yes. It works very well with an iPhone 4S. It should also work with any cell phone that is equipped with Bluetooth.

Yes. I use the charging cord separately and sometimes listen to the tunes on the 4S. This pretty much would work with any phone except possibly the very wide ones.

I have an IPhone 4s and it works fine. Pretty sure it works on a 4 and above.

This works fine with an iPhone 4s and has been tested working with an iPhone 4. I bet it would work with an iPhone 3gs.

Yes, it will work for iphone 4 and 4s, it doesn't matter whether its sprint or verizon it will work anyways.

It plugs into the headphone jack so it should work with the iPhone 4 but honestly you would be lucky to get it to work at all.

Yes! It should work fine! Your iPhone 4s has the same ios system as the iPad. Therefore it uses the same blutooth technology and will connect perfectly;

I don't happen to have an iPhone 4S, but it just has the things you plug into the wall, along with the standard chargers. SO if you have an iPhone 4S along with the part of the charger that goes only from phone to wall outlet, it would work!

Yes, it worked with my iPhone 4S, but not for long. It died after about one month. Good luck!

It works with an iPhone 4S. If I remember correctly we had to read the instructions twice to figure it out but when I went back and looked I couldn't remember why. Best of luck to you.

I know it works on the iPhone 4 which is what I fixed. If the 4s case is the same it should work. I think you can find the exact dimensions of the phones on the apple website or just google it.

I have a 4 and it works just fine. I would suspect it would work just fine with a 4s

It should. It only uses the headphone jack which means it shouldn't be an issue when using an iPhone 4S. I've used it with an iPad 2 and a Sony Xperia Z, and with my friends' phones as well.
