Since the world's engineers haven't yet come up with a way to read minds over the internet (or at all, last we checked), we're not sure what you think about the proposed marriage of T-Mobile to AT&T. We're pretty sure you do have an opinion of some sort, though, and if you want it to be heard, now's the opportunity to let the Federal Communications Commission read your thoughtful, reasoned take on how a GSM monopoly in the United States might or might not work. (Speak now or forever hold your peace, in other words.) To comment, simply visit the source links below, where the FCC has some handy forms -- one for short comments, one for long comments (where you have to attach a PDF document) and one with the magic number of the related proceeding, which is 11-65. Let 'em know just how you'll be impacted if the deal goes through, for better or for worse.
