The first iPhone with Retina display, Siri, and a steel body
iPhone 4 marks the inception of high-resolution displays, branded by Apple as Retina. Meanwhile, the 2011 debut of iPhone 4s introduced the world to the first virtual assistant, Siri. Back then, Retina was a compelling hallmark of quality. Transitioning from the iPhone 3GS to the iPhone 4, I immediately fell in love with its screen. With double the pixel density, every detail appeared crisp and smooth, unrivaled at the time. Even now, Apple retains the Retina moniker, maintaining a balance without overly inflating resolutions like modern Android devices. Overall, it delivers a solid user experience without unnecessary extravagance.

Memories with iPhone 4
I've owned iPhones since the first generation, but the iPhone 4 holds more memories for me than any other. Even buying the device was memorable. Back then, there weren't as many stores selling iPhones, and getting one was challenging due to high demand. I remember mainly relying on network providers to purchase, where you'd draw lots for a chance to buy at places like Vinaphone or Viettel.


Is it still usable?
