Will this work with an iPhone 4S?

Yes. My husband has a 4s that works just fine with it. I have the attachment for my 5 that works really well too.

Kinda sorta...it plays, but displays a message that the unit is incompatible with the device. Had I known this, I wouldn't have bought it.

I'm not sure what your concern is, but as long as your phone has a 30 pin connector port, it should.

I bought this product for my Verizon MiFi as it was compatible to plug into. I don't think it would work for your iPhone 4s.

Yes, it work with IPhone 4S. Go to setting of the IPhone 4S and touch the bluetooth and at the same time press the bottom of the headphone to let the Iphone search. Try this several times and it will activate.

It should. Just make sure that the output matches the charger intake. I used the plug that came with my iPhone 4s and it worked fine.

There is no such thing as an "iPad 4s." It should work on any iDevice with a lightning connector, but I can't determine which model you are asking about.

It should work fine for you. I have the iPhone 4S & I have no complaints. I have been using this for about two months now with no problems.

Absolutely works on the iPhone 4s - can't say if it works on the iPad since I don't have one. If the port/cable are the same, then my guess is it should work.

It works very well with the IPhone 4S. It only takes minutes for it to charge. I love it.

My iPhone 4s works fine with it, and I think it should work with an iPhone 4.

It will definitely work for an iPhone 4S (that's what I have). As long as your charging port is accessible through the case, then it shouldn't be a problem.

According to the product documentation, it will not. It will only work with 4S and up.

I don't know for certain. I can tell you that it did work with the iPhone 4S even though the packing materials seem to say no. Please read my review on the issues I found with it - I did return mine to the store where I purchased it. If nothing else be sure you can return it.

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.

Yes. I have used this with several smartphones including the iPhone 4s and it works perfectly.

well, I would think it would work with the iphone 4s I believe the connection ports are the same as the ipod touch

Yes, it works with the 4S. Reception varies depending upon the area though.

It worked on a 4 and not a 4s, so I would say no. I picked one up from Lowe's for about $5, and works great.
