You can always count on the Android ROM development community to extend a device's relevance in the tech world. Take the OG Galaxy Tab for example - this little guy was the first Android tablet to hit the scene (running a phone-specific version of the OS, no less). It has been around for about a year and a half now, and there's no hope that it will ever officially be updated to anything past Gingerbread.
The official OTA for the GSM version of the original Galaxy Tab just started rolling out, and Chainfire over at the XDA forums has already pulled the update, rooted it, and made it available for your downloading pleasure. There are two different versions of the download - one with a new bootloader and one without. While I didn't read the entire thread, it appears that most users had better luck with the version that includes the bootloader.
