Bharti Airtel has been allowed to ‘unlock’ its 3G iPhones by Apple enabling the Indian company to sell it through their stores to any user, not necessarily only an Airtel subscriber. According to Apple’s global support site, Bharti Airtel has been authorised to legally unlock the iconic handsets in the country. Vodafone in Australia, Orange in Austria and Movistar in Argentina are among the 40 global carriers authorised to unlock the handsets. In India, the 8 GB model costs around Rs 31,000, while the 16 GB is priced at Rs 36,000. Apple will also launch the latest version, iPhone 3GS, billed as the “fastest, most powerful iPhone yet”, on August 9.
