Can i download things on my iPhone 4s over 3G?

I wanted to know can i download apps over a 3G connection?
Also, what happens if I updated to ios6 on my iPhone, not through iTunes but directly on my iPhone, will it delete all my apps so i have to go on itunes and restore it?

You can but depending how big the app is, you may need a Wi-Fi connection as some games or apps can be pretty big in memory size. If you update to ios 6 on your phone, won't lose any apps. I did it on my iphone and just takes about 10-20 mins, depending how many apps you have.

  • Why is my iPhone copying the same video over and over? So I took a screen recording earlier today and when I went to send it, there were about 50 of the same video. I thought alright i'll just delete them. So I did. And they returned. I now have over 300 of the same video and it keeps copying itself.
  • Why does Netflix keep pausing and playing over and over? I'm using it on my iphone 4. And I have checked my connections over and over I've uninstalled reinstalled, signed in signed back and everything else that the troubleshoot website has recommend. And it's gotten annoying. It didn't start doing this as much until I updated the app before the ios 7 release. I'm currently using the trial for netflix and my laptop doesn't work so I can get it on anything but my phone.
  • My iphone rebooting over and over? My iphne has been reboting itself. Its on for a few minutes but it just boots it self again. I tried every method but non of them work. I need the method for iphone 3g ios 6
  • My iPhone 4S keeps vibrating over and over for no reason? It does it like every 10 minutes for about 30 seconds. It's almost like getting a notification every second. I'm not getting any notifications though, it's just vibrating for no reason whatsoever… What's wrong with it?
