After introducing the phone to the Indian market in January this year, The Times of India is reporting that Apple has reversed this decision, once more discontinuing the product which was originally released in June 2010.
The paper says that new supplies of the iPhone 4 have been terminated at three leading trade partners in the country. It is weird for Apple to reverse plans so soon, but it was also uncharacteristic of the company to bring back the iPhone 4 in the first place.
Apple may have decided that the iPhone 4s and 8 GB iPhone 5c fills the gap well enough that it no longer needs to keep the iPhone 4 around. Despite expanding the availability of the SKU to more countries in mid-April, however, the device is not actually offered in India just yet. It is possible that the transition is still taking place.
