For Apple fans, tomorrow will likely be the most exciting day of the year. Apple is set to make some big announcements at a press conference scheduled for Sept. 10, and we expect the company to announce two new iPhones, the flagship iPhone 5S and the entry-level iPhone 5C.

The iPhone 5C announcement may be just a day away, but for now we’ve got a fresh batch of leaked photos courtesy of Sonny Dickson, who apparently got his hands on the device’s logic board over the weekend. The new component shows some minor improvements, including a re-positioned accelerometer. It’s still unclear what type of processor the 4-inch handset will come equipped with.

Based on previous leaks, the iPhone 5C will feature a plastic body with rounded edges, and will come in a variety of colors including green, yellow, red, blue, white and black. We have just about 24 hours until we know the final details.
