Does an Iphone 4 have hot spot?

& i heard that you have to pay for almost every app. Is that true?

Iphone 4 is the same exact thing as iphone 5 but iphone 5 is just faster and has a different charge plug - there are tons of free apps and it does have hotspot.

No, there's tons of free apps. You do have to pay extra per month for the hotspot though.

I'm using my iPhone 4 now it has no hotspot and every app I have cost nothing there are as many free apps as there are paid hope I helped

The hotspot function is not an app. Its availability is dependent on your carrier. You can turn it on in general settings.

  • Why can't I use Wi-Fi on my iPhone as a hot spot? I can only use my phones network carrier data and 3G when I go to use my phones hotspot and not Wi-Fi. I used to be with BT Wi-Fi but can't afford it at the moment. For some reason I'm Able to still use BT Fons on my phone for Wi-Fi. But can't connect it to my laptop. Any help would be appreciated
  • There's a blue spot on my iphone screen? It showed up a couple days ago and I don't know what it is. You can only see it when the screen is entirely one color but it still bothers me cause I just got this phone 2 weeks ago! I'm really upset? What do I do
  • There's a black spot on my iPhone 4 screen Ok so on the top right corner of my iPhone screen there's a black spot i don't know what to do I reset it already I'm sure I didn't drop it I swear and there's no water damage how do I fix this problem!
  • MacBook goes to sleep mode when iPhone placed in one spot? I noticed a few months ago that every time that I place my iPhone 5 on the space to the left of my MacBook track pad, it automatically shuts off all connections to my MacBook, and the laptop goes into sleep mode. I'm wondering if anyone knows why, or if this has happened to anyone else. I just find it really weird since I have no other problems with the MacBook or the iPhone. P.S. - This did not happen with my iPhone 4
