The staff at highlight three not-so-obvious ETFs that may benefit from the launch of the iPhone 5.

Apple's (AAPL) iPhone 5 debuted this week. While Apple is an American company, it is also a global powerhouse. California-based Apple posted fiscal third-quarter revenue of $35 billion, with global sales representing 62% of that figure.

In fiscal 2011, the iPhone accounted for 40% of Apple's total revenue, making the smartphone the company's most important revenue driver. The iPhone is also Apple's most important way of bolstering its presence in foreign markets and adding exposure to new international frontiers.

All eyes will be on Apple's stock and some of the obvious technology-heavy ETFs such as the PowerShares QQQ (QQQ) and the iShares Dow Jones US Technology Fund (IYW) following the unveiling of the iPhone 5.

But we’ve found a few international ETFs you may not have considered that will also benefit from the Apple buzz and rising stock price. These ETFs also offer a way of gaining exposure to Apple's long-term international growth plans.

1. iShares MSCI Mexico Investable Market Index Fund (EWW)
The iShares MSCI Mexico Investable Market Index Fund makes the list not just because Mexico is one of the smartphone markets in the world, but because of the ETF's 22.4% allocation to America Movil (AMX). Here is a recent daily chart:

America Movil is Latin America's dominant wireless carrier, and smartphone sales and usage are accelerating throughout the region. Smartphone sales accounted for 20% of mobile handset sales in Latin America last year, and the number is expected to reach 46% by 2016.

The iPhone is already available in 17 Central and South American nations. America Movil had 246 million subscribers in 18 countries in the second quarter, making the company the prime beneficiary of Apple's future Latin American growth.
