Complex Magazine made a video called 'Hold My Phone: The Evolution of Mobile Devices in Rap Videos' documenting cell phones use in rap videos over the ages. It's pretty cool to see not only how far phones have come, but how far hip-hop has come as well.
Using Ice T's "High Rollers" video as a starting point, he Motorola Dynatac is the first phone we see. Other phones include the T-Mobile Sidekick, BlackBerry Curve and the most recent iPhone 5s.
Some of the biggest hip-hop artists of all time use cell phones to show their status. It's interesting to note how at first, it was enough to just have a cellphone regardless of what make or model it was. Now, it's all about which model you choose to represent yourself or sponsors.
