Palm InfoCenter’s “Pirated Upgrade Brings OS 4.1 to N710C” article last Oct 08 states that Sony strongly advises people against performing the self-upgrade. A company spokesperson made it clear that doing so is a violation of the handheld’s warranty. The next day, Sony Announces an OS Upgrade Program for the Clié N710C from Palm OS 3.5.2 to the latest version, Palm OS 4.1. The upgrade will be done by Sony technicians. For $50, Sony will pickup the handheld, upgrade it, and return it with a CD containing all the apps that come with the N760C.
