POP, an accessory to charge multiple devices, used both a 30-pin connector and a Lightning connector. After a Kickstarter campaign that raised nearly $140,000 in funding, the project was roadblocked by Apple's MFi license that would not allow both charging specifications on the device.
"When Apple officially announced the move to Lightning we determined the best course of action was to incorporate two Lightning chargers, and two 30-pins (along with the four micro-USB’s). After applying to Apple (which is now required for Lightning), we learned that they are no longer willing to approve a product that uses the Lightning charger alongside any other charger (including their own 30-pin — seriously). Just like that, POP could no longer fulfill its true promise."
Creator Jamie Siminoff recently announced that he would refund the project's backers at considerable expense; however, following the negative publicity over the matter, Apple has updated its guidelines.
"Our technical specifications provide clear guidelines for developing accessories and they are available to MFi licensees for free," Apple spokesman Tom Neumayr told CNET. "We support accessories that integrate USB and Lightning connectors, but there were technical issues that prevented accessories from integrating 30-pin and Lightning connectors so our guidelines did not allow this."
The company noted that these guidelines have since been updated to allow accessories to work with both types of connectors to charge devices.
