From Tin Cans to Touchscreens: The 40 Most Important Phones in History
Motorola RAZR V3
Motorola sold more than 50 million RAZR phones in its first year of release, making it the most popular clamshell cell phone of all time. The RAZR boasted a stylish design, super slim profile, and a few relatively uncommon features for its time, including an electroluminescent keypad.

Other luxurious features included a 2.2-inch TFT LCD screen, 10MB of internal memory, MPEG-4 video playback, and an external color screen. Five years ago, this was the phone everyone wanted. And today? It means you're lame and woefully out of date.

F-1000
Built by UTStarcom, the F-1000 was Vonage's first Wi-Fi phone, which meant that Vonage subscribers could make calls from any open hotspot.

Early units were buggy and a little bit difficult to configure, but even still, most considered the pairing of a Wi-Fi phone with Vonage to be a winning combination. The woohoo jingle? Not so much.

First Cordless Phones for Skype
Skype rocks for a number of reasons, not the least of which is the ability to make free and low-cost phone calls all around the world. The downside? Being tethered to your PC. That all changed when phones for Skype were introduced.

In 2006, Skype announced the first cordless phones compatible with its VoIP software, including the Philips VOIP841 and Netgear's cordless phone. Cordless handsets were the logical next step for Skype, and gave cheapskates penny-pinchers a viable alternative to Vonage.

Around the same time Skype announced the first batch of cordless phones for its VoIP software, the company also unveiled its first Wi-Fi phones, including one each from Belkin, Edge-Core, Netgear, and SMC. Each phone came with the Skype software preinstalled and could store contacts and display who was available to talk. To make a call, you just needed to be in range of an open access point.

Apple iPhone
No matter how you feel about Apple -- and trust us, we know how MPC readers feel -- the iPhone ranks as arguably the most important smartphone of all time.
A newcomer to the cell phone business, Apple took the mobile world by storm when it introduced the iPhone in June 2007. Much of the hype centered on the iPhone's touch interface, and while it wasn't the first smartphone to sport a touchscreen, it was the first one to get it right. Not only was the interface mostly responsive, navigation was a breeze.

The iPhone also played a integral role in promoting the mobile app market, and espeically in the success of Apple's App Store, which surpassed the 3 billion download mark in the first week of 2010.
Not without its weaknesses, the iPhone received criticism for its short battery life, proprietary battery, and tight integration with iTunes. Nevertheless, Time Magazine dubbed the iPhone the "Invention of the Year," and we'd have to agree.

HTC Dream (T-Mobile G1)
Apple wasn't the only one hot to trot in the mobile market, Google wanted to jump in the ring too. But instead of developing a handset of its own, Google continued to work on its open-source Android platform, now the fastest growing mobile OS on the planet.

HTC's Dream, or T-Mobile G1 as it's known in the U.S. market, became the first smartphone to run Google's OS, prompting many to wonder if this would be the iPhone killer. The G1 didn't live up to that designation, but it did introduce the world to Android and Google's Android Marketplace.
Thanks to the Android platform, the G1's greatest attribute is its open nature. It didn't take long for modders to start churning out third-party ROMs to address the handset's shortcomings, like the inability to install apps to an SD card instead of the paltry amount of internal memory.
