XM first announced that they were creating an official XM Radio client for the iPhone and iPod touch back in June, but little was heard from the company since then on an official app. More recently, however, information was leaked that GeeksToolBox is working on an app called StarPlayr as part of the StreamSmart project. It is suspected that it is in partnership with NiceMac because of their audio streaming Mac app by the same name.
Millard Software has announced that they are currently working on porting their two satellite radio clients, uXM and uSirius, to the iPhone OS 2.0. Neither of them are official applications yet, so they will only run on a jailbroken phone, but both of them will work on EDGE, Wi-Fi, or 3G. With all the talk of a merger, it is hoped that they will soon turn their attention to the iPhone, but either way Millard Software is porting the apps using the SDK. They may try to launch them on the App Store if possible.
