According to world-renowned financial analyst Mark Moskowitz, the iPhone 5 will without a doubt be the most popular phone of 2013. The new iPhone is set to release in September, and production around Christmas time is expected to double. The new iPhone allows for 4G LTE networks to work at optimum levels, and other upgrades guarantee that the iPhone 5 will dominate the market.

“We think that a combination of revolutionary hardware enhancements and software-driven services stand to reaffirm the iPhone as the leading smartphone in 2013,” Moskowitz wrote.

However, a few challenges do face Apple leading up to the release of the iPhone 5. JP Morgan is already beginning to adjust their second-quarter sales and earnings estimates, and they aren’t good adjustments. The financial company’s new data seems to suggest that Apple will be facing the hard times that are looming in the future for hardware vendors. JP Morgan also lowered their projection of iPhone sales, but that isn’t uncommon; a new model is being released soon, and people are holding off on buying the iPhone 4 in anticipation of the iPhone 5.

In good news for Apple, JP Morgan has also increased their predictions for sales of the iPhone 5 by a significant margin. The reports indicate that if the iPhone 5 sells well, the MacBook series and iPad series may begin to drop in popularity. “Overall, our expectation of stronger iPhone unit sales and the related mix benefits partially counters our lower growth assumptions for the iPad and Mac businesses,” Moskowitz wrote in his investors note released earlier today.

Happy birthday, iPhone – tomorrow will be your fifth birthday. To date, Apple has managed to sell a smidgen over 218 million iPhones, resulting in $150 billion in sales.
