no its like any other phone none need wifi
No you do not need WIFI to use the iPhone. The iPhone works with either 3G or WIFI. Some apps require WiFi to download or run depending on their size. I find wifi works best though and is faster. YouTube videos are extreemly clear and crisp with wifi.
Any where that WiFi is available. There are no restrictions.
You can text and even video chat if you have Skype. And yes you can call but it's illegal.
