I'm thoroughly perplexed by the decision to offer iOS 8 to the 4s, which also has BTLE, and yet castrate it from watch support. I'm grasping for a technical reasoning that satisfies my curiosity on this one. I like upgrades, too. But I just got this phone from my carrier in Feb. Then I purchased $100 in accessories that only fit this phone. Now what I seem to be facing is spending $200 for another upgrade; To use a $349 watch. Can anyone elaborate on why this may have been done from a hardware requirement perspective? I didn't see this one coming.

If nobody here can offer definitive (or 'official' ?) answers, then technically all answers are speculation. If people are not allowed to answer, and Apple will not answer, why are we here? Community typically involves interaction and your statement voids that notion. I'll email Apple and ask directly. I wasn't aware that questions about device support, in a support community, were prohibited. Apologies. Good night.

That is a pain.


I hoped too that as it has iOS8 on the cards that it would be able to talk Apple Watch.


I've read somewhere that iOS8 will not have all the features that the 5 onwards will get, but I suppose that's not surprising. To get iOS8 though is good.

That doesn't answer the question of what the tech reason is, if there is one. Could even be something as silly as it impacting battery life or something, who knows.

I can't obviously say anything here but there are multiple ways to use AppleWatch with iPhone 4s. Just wait for it to be officially released and do your Google search a month later "How to pair AppleWatch with iPhone 4s". I never used 3rd party apps etc, but apple is pushing me to that direction, to use them, because they disrespect their customers. iPhone 4s technically can pair with apple watch, but apple wont let this happen... I wonder why...

The iPhone 4S can not use LTE, just 3G. I am such a power user that when my area upgraded to LTE, my phone was upgraded to a 5S for free. The 4 also sports an A5 chip that uses the older Cortex A9 core. For the 4s, the A5 chip is clocked at 800 mhz. In comparison, the 5S is 1.3 to 1.4 ghz and uses a newer Cyclone chipset. There is also the 32-bit iPhone 4 architecture vs. the 64-bit architecture of the iPhone 5. I suspect these are the reasons the iWatch requires the iPhone 5 or greater.
