HTC Hero Android 2.1 update imminent tips OTA firmware tool upgrade [Update! Official HTC statement]
HTC are paving the way for the promised HTC Hero Android 2.1 firmware update to European handsets, though the new OS package itself is not yet in the wild. A new OTA update for the Hero has been announced which upgrades the smartphone's "Firmware over-the-air (FOTA) client" (along with making unspecified tweaks to the YouTube player app); that's likely the first part of what we've previously heard is a two-stage update process.
Update: HTC has been in touch with an official statement - find it after the cut.
