Yes! Apple recently released the iPhone 4 on Verizon wireless. These Verizon iPhones come with Verizon's built in mobile hotspot feature though it must be activated through Verizon and incur additional costs. And as of March 11 with the release of the iPad 2 and the subsequent iOS 4.3 release the AT&T iPhones can also broadcast wifi to up to three devices. This new feature applys only to the AT&T iPhones since the Verizon iPhones already have it. It must also be activated through AT&T and will incur additional charges. But to sum up the answer to your question, Yes! iPhones can broadcast wifi to other devices at additional costs from your service providers.
If you have wifi
The ipod touch 4g can video chat with an iphone 4 if you have a WiFi connection.
If you just connect a router to your iPhone, then the Internet should be free.
Yeah. I'm sure all iPhones do.
No software is required to use Facetime on the iPhone 4. It is required that you be on a WiFi connection. Facetime can only be done from one iPhone 4 to another iPhone 4. If you are using Facetime on a jailbroken iPhone then it is possible to Facetime chat with out using a WiFi connection. Simply go into Cydia and search for a package called My3G. This app allows you to trick your iPhone into thinking is it on Wifi connection allowing for Facetime chat over a 3G connection. An alternative to using Facetime would be Skype. Skype can be downloaded in the Apple App Store. Skype is video chat that can be done from iPhone 4 to iPhone 4 or iPhone 4 to a computer or computer to computer.
Any where that WiFi is available. There are no restrictions.
How Do I get my wifi network back on my iphone
No.
No...you don't need wifi for the American idol app for iPhone.
yes, you can just use wifi access to use the Internet on your iPhone
Use open the app if you are on iOS 6. If you are not on wifi then it will fall back on your cellular connection (3G or LTE). The only problem is that AT&T blocks this feature on iOS 6 unless you have their shared plan
yes
