The display of the iPhone 4/4S, when compared with that of any tablet, it is really too small, so watching a movie is really uncomfortable, and this may guide you to buy an iPad or a future iPad Mini. You have another option which will not cost you much, buy Mini Cinema, a strange lens that magnifies the screen of our iPhone without sacrificing quality or design.
The Mini Cinema consists of a Dock, a special Horn to amplify the volume of your device and a lens that magnifies the screen of your iPhone 4/4S.
Unfortunately we won’t be able to interact with the touchscreen. If you are a fan of the movies or simply want to have a digital photo frame without spending a lot of money this accessory for you.
You can purchase the Mini Cinema for iPhone 4 and 4S from this link in two different colors (white or black) at a price of $ 68.
