Apple released its quarterly earnings report on Tuesday, and included in that were slower than usual iPhone sales.

The latest rumor is that the iPhone 5 (and possibly the iPad Mini) will be released in September. This piece of rumorformation comes from analyst Ming-Chi Kuo, as reported by BGR.

Apple CEO Tim Cook and CFO Peter Oppenheimer spoke on the company’s earnings call, acknowledging that speculation about the device has hurt iPhone sales. Essentially, people want to wait for the next version, rather than buying one before it comes out.

“We’re reading the same speculation about a new iPhone as you are, and we think this has caused some delay in purchasing,” Oppenheimer is quoted as saying.

Still, it’s not as though Apple isn’t selling iPhones. The company still sold 26 million of them in the quarter, representing growth of 28% over Q3. Apple sold 26 million iPhones in the last quarter, which represents a growth of 28% year-over-year. They also happened to sell 17 million iPads (an 84% increase year-over-year).

Rumor has it that the iPhone 5 (which may not even actually be called the iPhone 5) is currently in the manufacturing stage. The device, no matter what it’s called, is also rumored to have a smaller dock connector than its predecessors, which will mean it won’t be compatible with many existing iPhone accessories.
