This was the first phone to feature built-in GPS. It was never commercially available in the United States.

2002: Samsung N620

2009: LG Xenon

Ah, the LG Xenon… It was a pre-iPhone phone in a post-iPhone world. A quick look at the archive of Amazon reviews of this phone reveal a few common issues including a finicky LCD screen and a tendency to snap in half.

2017: Nokia 3310 (again)

The Nokia 3310 has been reimagined for anyone who is nostalgic for a simpler time, way back around 17 years ago. The feature phone now has a color display but the 2017 phone still uses T9 texting, the camera is still 2 megapixels and, most importantly, you can still play Snake.

2017: iPhone 8

Comps of the 10th anniversary iPhone suggest that Apple will ditch the home button altogether in favor of on-screen navigation. Speculation and excitement continue to mount as whispers from Palo Alto suggest big improvements from previous iPhone models.
