Saying that we suggest you take this rumor with a grain of salt... that just might be the biggest understatement of the year. That's if you regard this as a rumor to begin with, and not for something as mere wishful thinking of some MGS4 fans.

While some of the other bloggers are currently gunning through an MGS4 marathon as I write this (man, I wish I could take their place), we've heard of talk that it might be possible in the future to upload your own music into the in-game iPod in Metal Gear Solid 4 from your very own HDD.

This was supposedly hinted at by an in-game podcast between Ryan Payton and Ken Iamizumi accessible by the in-game iPod. (Sorry, we're trying to keep true to Konami's spoiler-free restrictions on technical details.)

Anyways, if this proves to be true, how will this feature be implemented, you ask? Current speculation online holds PS3 Firmware 2.40 as the key to introduce the said feature. The new update is supposed to be released any time soon anyhow.

PS3 Firmware 2.40 is a bit of a wild card these days as it's already been rumored to incorporate in-game XMB access. Adding "music uploading" as another feature just makes our skin crawl. If all these rumors prove to be true, just how huge will this summer's update be? Talk about standing in the midst of pure awesome.

With that said, we'll give you guys updates as they roll along. So for now... Grains of salt, guys. Grains of salt.
