How does twiiter and facebook's mobile applications work and how would you recreate it?

[Patrick K]

I was wondering how a website is able to send texts messages out and also receive text messages. How does twitter work when you can text in and it be your status? The same with facebook where you can txt in pictures, messages, or videos?

Does it take a huge amount of programming or is simple?

I was wondering what it takes to recreate it. If anyone could connect me with research, a person to talk to, or an answer that would absolutely great. Thank you so much!!

It can take months to create a mobile phone app there are university courses in it which are 3 years long so imagine studying how to programme for 3 years just to develop a phone app. The complexity of a phone app depends on what it is for an example tetris would be simple where's sims 3 wouldn't be see what I mean so something like this would be difficult to answer.
