The Smart Trigger uses Bluetooth 4.0, which is only available on the iPhone 4S, iPhone 5, iPad Mini, iPad 3, and iPod Touch 5G.

Unfortunately I don't know. It definitely works with iPhone 4, iPad 3 and Samsung Galaxy Note 2.

No it will not this screen is meant to work with the iPhone 4 only. You would need a 4s specific screen.

Although the info online stated it worked on the iPhone 4, I have the iPhone 5 and it works fine with it. Not sure about older versions.

It will work with anything that has a headphone jack. So yes, it will work with iPhone. I hope this helps

If your phone is bigger than iPhone 4, yes. iPhone 5 and 6 or a Galaxy or a Note should all work

I have an iPhone 5 and it was not. If the 4 has the bigger connector, it should work.

I am not sure but I am pretty sure it will work. I use it with my Iphone 4. You should be able to buy an adapter if the 4s does not work. In the worst case scenario you can use 3.5mm jack to make it work. At the current selling price you really cannot go wrong. Good luck.

Yes it should. All you need for this device to work is bluetooth availability. As far as I know iPhone 4 does have bluetooth so thisdevice should work with iPhone 4.

No, it does not work for iPhone 4. The iPhone 5 is thinner and longer than the 4.

I'm not sure about the iPhone 4 but it fits perfectly on my 4s. If the two phones are the same size, then it will fit.

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

I have not used with iPhone 4, but I am sure it must do as the phone has Bluetooth. I am using mine with iPad 2 and Galaxy S2, friend using iPhone 5 and another using iPhone 3, so your phone will work.

It works with my 4s iPhone. I'm satisfied with it for the price. Doesn't answer your question but hope it helps.

No it will not work for the iPhone 4 but they do make a case just like this to fit the iPhone 4. I know this because before I got my 5 I had a 4.
