Gizmodo covered an app for the i730: it's a status light java app, which amazingly isn't part of the default UI. The author, Michael Blake, related a total horror story via email about distribution, hassles with existing Nextel publishers, and nasty, lying pirates who have preyed on him and his app. Without OTA download, he's left with cobbling together his own DRM and security scheme, and stuck with putting in *way* too much effort to release what is fundamentally a simple solution for a simple problem.
