CUPERTINO—At the first event held in the new Steve Jobs Theater on its new campus, Apple announced the new iPhone 8 handset today. This year marks the 10th anniversary of the original iPhone, and Apple celebrated by doing something very uncharacteristic: skipping the “S” iteration of the iPhone 7 and pushing full-steam ahead with the new iPhone 8 and iPhone 8 Plus models.

The iPhone 8’s design is based off the iPhone 7 in that it doesn’t look incredibly different than Apple’s previous handsets. The iPhone 8 and 8 Plus are similar in size to the iPhone 7 and 7 Plus, but they have new glass fronts and backs that nod to the glass construction of the iPhone 4. Both models are made with aerospace-grade aluminum and the glass is reinforced by steel. Each model has a Retina display as well for improved color accuracy, wide color gamut, and True Tone technology.
