Does it work with iPhone 4

No, iPhone 4 reaquires micro SIM, this standard size card, but you can cut it to micro size if you are determined.

If the phone is fully unlocked or locked only to ATT then there is no reason for it not working. I personally have done it with three android phones to date and they all work. I do get 4g in my area but I think the I4 is limited to 3G.

I don't think this will work on an iPhone 4. I would not reccomended it to anyone ever, for any phone!

Yes. It works with iPod iPad iPhone 4&5 and other Bluetooth capable devices. We had a little trouble getting it to link to my wife's new phone but after a couple of try's it worked great.

i'm not sure it if is, you have to download an app for it which I am not sure if it's compatible with the iPhone 4.

It works on my IPhone 4. There is some static and sometimes you lose the signal. It also charges your phone. Very clumsy though as unit does not detach from stalk.

Yes. I have it working with am iPhone 4. I would suggest getting the Bluetooth kit instead. It is cheaper and works with more devices. It won't, however, charge the device. Not sure about controlling the music either(ff rw pause etc)

Hello Igor. I wish I knew the answer for you. I do not have a Iphone 4 myself but I believe that all the connections in the new tech toys seem compatible. I would give it a try. Happy Holidays.

Sorry, but it did not work for me. Not for iphone 4, iphone 5 (different usb adapter), galaxy S4 (micro usb) nor galaxy note 3 (usb 3). It is basically useless.

It should work with an iPhone 4 if it has a 30-pin connector. I never had an iPhone before, hence I am not the best person to help you. However, I do know that iPhone 5 and 6 would need a lightning to 30-pin adapter to work.

It will NOT work with iPhone 4 or the iPad 2. Those both have Bluetooth 2.1. However the iPhone 4s, iPad 3rd gen, iPad Mini and all newer devices will work as they have Bluetooth 4.0.

It should as long as the iPhone 4 is Bluetooth capable. I don't know for sure though because we both have 5's

Yes, it does. It works with my wife's iPhone 4, as well as my iPod Touch 3rd gen. And the sound is awesome!

It should work fine with an iphone 4. It works through bluetooth and should pair with any device with bluetooth turned on. It pairs easily with my iphone 4s and iPad. It has been a nice speaker. The microphone could be better for conference calls but the speaker works great.

yes, it worked with my iphone 4. it will not work with the iphone 5 series, even with the adaptor. I just found that out recently.
