Will this work for the iPhone 4 or 4s?

There are ones designed for iphone 4. Because the position of the speaker is different for iPhone 4 and 5, you need to get the one designed for iPhone 4.

It sucks. It barely boosts the audio. And it only works if your iPhone is not in a case. It has to be just the iphone. If your phone has a protective case, it won't fit.

I don't have a 4s but guessing from my 3GS and my 5s that the drivers work on both of them that it would be safe to say it will work on your 4s. Hope have helped

This product will only work on the 4S NOT THE 4!!! Get the iPhone 4 screen with your corresponding carrier.

Yes, this product works perfect for the iPhone 4s. It is most definitely worth the purchase

this will work for IPhone 4s .. just beware that this is soft leather and stitching is close therefore may tear-up easily

My opinion...iPhone 4S and iPhone 4gs are pretty much the same but the 4gs has more memory .As far as using this phone case, YES it will work on either iPhone 4.

This was installed on a 4S and works perfectly. I can't say if it would work on a 4 as I have not tried to install it on one.

I used it on my iphone 4 and it worked well, not sure if it is the same for 4s.

I think the 4s and 5 have the same charger, so if that's the case, then yes it will work. It just sits right on the charger thing. Sorry for not knowing the exact terminology. lol good luck

This particular one is for the iPhone 5, so it won't work with a 4 or 4s because they are physically smaller phones. They do make otter boxes for those phones though, so try searching for one by model number.

Yes, I currently use the 4S with it, not sure there is a difference between the 4 and 4S when it comes to the adapter compatibility.

I don't know. The plug fit my iPhone 4, so if the same charger plug will fit a 4s you should be good.

Book Boy, yes it will work with iPhone 4S. I have an iPhone 4S and it works great, it was very easy to connect to my iPhone via Bluetooth.

Iphone 4s and 4 are the same size, so it works for either. We use it on a 4s.

An answer placed here by another user is incorrect. The correct answer is "yes" it DOES work. iPhone 4S uses this products connector sizes on both ends.

Yes it will, the iPhone 4, and 4s are the same phone even if it is an 8gb, 16gb, or 32gb, they are all the same phone on the outside.

I've used it with an iPhone 4 and an iPhone 5 (with 30 pin adapter) successfully - so yes it should work with a 4S.
