Ever since its release, the iPhone 4S has been enveloped in a cloud of 'controversy' - Siri outage, the possibility of Siri's hack and port to Android devices and laptops,and a battery-sapping iOS 5 update. That's not all - Engadget has reported that several users have been plagued by issues with their SIM cards, prompting that the smartphone might, once again, contain a design flaw.
Engadget - While we have no reason to believe a majority of iPhone 4S owners are affected, the problem appears to span across numerous carriers and parts of the globe -- even Sprint and Verizon Wireless users aren't immune.
