No 3G video calling on iPhone 4

Users in India can make video calls using WiFi, but not over 3G as the application that enables the service has been locked by Apple.

The Apple iPhone 4, which is being regarded as the most unique device, is not capable of making video calls over a 3G mobile network despite being a 4th generation smartphone.

Users in India can make video calls using WiFi networks, but not over 3G as the application which enables the service is locked by Apple.

The Apple spokesperson in India said, "FaceTime, the application that allows video calling on the Apple iPhone 4, is a closed user application that allows people having iPhone or compatible Apple hardware like the iPad 2 and forth generation iPod touch running FaceTime application to have video calling."

Airtel 3G plans

Airtel had five lakh 3G mobile subscribers within seven days of launching 3G services, that too from just five cities. What makes it click with users? Here is an analysis of Airtel's 3G tariff plans.

Bharti airtel had five lakh 3G mobile subscribers within seven days of launching third generation telephony services(3G), and that too in just five cities. Now it has over two million 3G subscribers (as of April 6) in 34 cities and towns across India including Bengaluru, Mumbai, Chennai, Coimbatore, Mysore, Manipal, Udupi, Jaipur, Delhi NCR, Hubli, Patna, Hyderabad, Agra, Dehradun, Meerut and West Bengal.

What makes it click with users? Here is an analysis of the operator's 3G tariff plans:

Airtel has a range of tariff plans for 3G customers, starting with a Rs 11 plan which gives 10 MB of usage for a day. The plans go up to Rs 750 for 2 GB data over 30 days.

But the sad part is that there are no real unlimited plans to choose from. As an alternative, the teleco is offering a Rs 675 plan, in which you get 1.25 GB data at full 3G speed, consumable over 30 days. Once you have consumed that, your access speed will drop to 20 Kbps and you will be charged 1 paisa for every 100KB till you reach a bill of Rs 2,000.
