The iPhone 3GS was the third iPhone model released by Apple. It used the iPhone 3G as its basis and fine-tuned some features, while adding a few others. Perhaps most importantly, though, it was with the 3GS that Apple established the naming and release pattern that it's used for the iPhone ever since.

At its release, it was said that the "S" in the phone's name stood for "speed." That's because the 3GS has a faster processor than the 3G, leading to double the performance according to Apple, as well as a faster 3G cellular network connection.

In the media arena, the iPhone 3GS sported a new camera that boasted 3-megapixel resolution and the ability to record video, which was new to the iPhone at that time. The phone also included onboard video-editing software. The iPhone 3GS improved in battery life when compared to the 3G and doubled the storage capacity of its predecessor, offering models with 16 GB and 32 GB storage.

The 3GS and the iPhone Naming/Release Pattern

Apple's pattern of releasing new iPhone models is now long established: the first model of a new generation has a new number in its name, a new shape (usually), and major new features. The second model of that generation, released the next year, adds an "S" to its name and sports more modest enhancements.

This pattern was most recently demonstrated with the iPhone 6S series, but it began with the 3GS. The 3GS used essentially the same physical design as its predecessor, but made under-the-hood improvements and was the first iPhone to use the "S" designation. Ever since, Apple has followed this pattern of iPhone development, naming, and release.

This pattern has been broken a few times. Apple never released an iPhone 7S or 8S, and most recently it introduced the iPhone XR in 2018 after the iPhone X in 2017. Still, more often than not, this is the naming and product-release pattern Apple uses for the iPhone.

Critical Reception of the iPhone 3GS

As with its predecessor, the iPhone 3GS was generally well received by critics:

  • We gave the 3GS 4.5 stars and said "the iPhone 3GS is the best iPhone ever ... If you’re not an iPhone user, it’s the most compelling reason yet to switch."
  • CNET awarded the phone 4 stars, but was a bit more restrained in its praise: "It's enough to get our attention, but not enough to get us completely excited."
  • Macworld rated the 3GS as 4.5 stars, saying "Apple is still leading the pack, in most cases by a wide margin."
  • PC Advisor gave it a 4.5-star review and raved "Best handheld computer ever."

iPhone 3GS Sales

During the period that the 3GS was Apple's top-of-the-line iPhone, sales exploded. Apple's self-reported sales of all iPhones up to January 2009 was 17.3 million phones. By the time the 3GS was replaced by the iPhone 4 in June 2010, Apple had sold over 50 million iPhones. That's a jump of 33 million phones in less than 18 months.

While it's important to understand that not all the sales in that period came from the 3GS — some iPhone 3G and original models were still being sold — it's fair to assume that the majority of the iPhones bought during that period were the 3GS.
