Will iOS5 become obsolete soon?

So I'm planning to buy a second hand iPhone 3Gs and I'll probably have it on iOS6 already. But I want to know how long apple will keep supporting iOS5/6 so that this phone doesn't go useless.

Ios 5 is pretty much on its last leg MANY apps no longer support it but ios 6 will still have lots of app support for another couple year most likely

It may be soon, may not be. Right now the de facto lowest version is iOS 4.3. No timetable to say when exactly.

  • Will the iPhone 4s become outdated soon? I'm an Android user that soon wants to switch to an iPhone. I've been hearing things about the iPhone 4 being outdated. Like updates or major gaming won't work on it. I'm planning on getting the iPhone 4s, but I'm worried it will soon too become outdated? Should I just pay the extra money for a 5?
  • Why is my iPhone 3g obsolete? I have had this phone for quite some time, and I understand they want you to get the iphone 4 or 5 but I don't really have the money or want to spend it on a new one when my old one works as far as calls and texting etc… But no apps work, one by one they are starting to fail, won't load, etc. I had instagram since I got my phone and it stopped working and I'm very annoyed with Apple!
  • Why does my iphone stays at IOS5.1.1 and won't allow me to update? It is already released iphone IOS6 for days but my phone stays at IOS5.1.1 and it says software is up to date but i know it wasn't. What should i do for me to update it?
  • When will the iPhone 4S become obsolete? I was wondering when the iPhone 4S will become truly obsolete. I can't afford a new model, so considering that it will be supporting the new iOS 8, how long should it take for Apple to stop pushing updates to it and seize production of this model?
