Apple iPhone 3GS - Third Generation iPhone (2009-2010)

iPhone 3GS

The iPhone 3GS, unveiled in June 2009, was the third generation of Apple’s smartphone and the very first to use the letter "S"—which stood for Speed. While it looked exactly like the previous iPhone, it packed a much faster brain and double the memory. This made everything run smoother and allowed for new features like home screen wallpapers and running multiple apps at once. It introduced a camera that could finally record video, a built-in digital compass, and basic voice controls. The 3GS was also the first iPhone to feature a special smudge-resistant coating on the glass to protect against oily fingerprints. It stayed popular for years as a budget-friendly option before being retired in 2012.
