In a similar vein to a recent mention of a Verizon trick which attempts to force the user to use an expensive data service to check e-mail, rather than the free built-in WiFi, Uninnovate discusses the (Sprint) LG Fusic which not only disables on-phone features such as MP3 playback when no coverage is available, but also has no way for users to opt out of (or reverse) firmware updates, even when they cause the phone to become inoperable.
