An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail. Other functionality, such as video games, reference works, and social networking, can be enabled by downloading mobile apps. , Apple's App Store contained more than 2.2\u00a0million applications available for the iPhone. Apple has released eleven generations of iPhone models, each accompanied by one of the eleven major releases of the iOS operating system. The original first-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations.\n"}, {"role": "user", "content": "I love my iPhone, I don't know if I could switch to another brand now."}, {"role": "assistant", "content": "I totally agree.

But I'd thought of buying them Samsungs."}, {"role": "assistant", "content": "Samsung owners like their phones too, so that's not a bad idea.  It's hard to believe that my first cell phone could not shoot video, take photos, play music, send email, browse the web...etc.  It really amazes me how far phones have come."}, {"role": "user", "content": "I know - and it was kinda big, then they got really small, and now we are back to being big again."}, {"role": "assistant", "content": "That's true!  The X is much larger than my 6.  I will have to get used to the size. "}]
