iMore first reported late last month that Apple plans to hold a media event on Sept. 12 to introduce the much-rumored, next-generation iPhone and new iPad mini. Today, iMore is adding more information regarding what we can expect from the event. It claimed sources have indicated Apple will update its entire iOS device lineup to support the new, smaller dock connector.

According to iMore:

iMore has learned that Apple intends to update their entire lineup of iOS device products to support the new, miniaturized Dock connector, and to do it as early the rumored September 12 special event this fall. This would include the new iPhone 5, the the new iPod nano and iPod touch, the rumored 7-inch iPad mini, and an updated version of the current 9.7-inch iPad.

iLounge reported last week Apple would update the 9.7-inch iPad with a thinner design, smaller dock connector, and a new backside mic while also addressing heat issues. iMore’s sources agreed that Apple plans to bring the smaller dock connector to the new iPad, but it is unclear if this would be a refreshed third-gen iPad or an iPad 4,1. Earlier this month, iMore also claimed Apple plans to sell a 30-pin adapter for the new smaller dock connector that will allow new iOS devices to work with old 30-pin accessories.
