There’s little doubt that an iPhone 5 will be unveiled this year, and a Verizon-specific model of the current iPhone 4 could arrive even sooner. A newly leaked video of some altered iPhone components seem to indicate one or both are already being manufactured.

BGR is reporting on a nearly six-minute video that hit YouTube on Wednesday from a company calling themselves GlobalDirectParts. The extensive video details a series of parts from what they claim is the next-generation iPhone -- although there seems to be some question as to whether this is a tweaked iPhone 4 (perhaps for CDMA carrier Verizon Wireless) or subtle changes that will be introduced with the iPhone 5.

Most notably, the video features a revised casing in gory detail, compared side by side with the current iPhone 4. It appears Apple may have tweaked the case to avoid the widely documented “death grip” issues from Antennagate, and the mute switch appears to be just a hair lower than the current model.

The case also contains the micro-SIM slot present in the iPhone 4, which is intriguing when you factor in the possibility this is a handset targeted for Verizon Wireless -- their existing CDMA doesn’t use a SIM card at all, with the exception of a handful of “global” models that are capable of operating on both CDMA and GSM networks around the world.

BGR notes that the whole video could be nothing more than a fake, but it’s quite an elaborate one if that’s the case. GlobalDirectParts also teases viewers that more is coming next week -- but in the meantime, have a look and weigh in with your own thoughts on its validity.
