If you’ve been looking for a way to get your XM Radio fix while rockin’ your iPhone, we’ve got a bit of news that might make your day. Millard software has just released version .53 of uXM for the iPhone, which should bring most of the functionality of a standalone XM radio to your iPhone handset. For those of you with sharp eyes, you might notice that this is, in fact, the same company that brought us uSirius. They did a great job with their first iPhone satellite radio app, and this looks to be as good or better than their initial effort. An XM subscription is required, but if you’re not a satellite radio subscriber of some sort by now, we’re pretty sure there’s no hope left for you.
