With reports that the first stage of the HTC Hero Android 2.1 upgrade was underway, HTC has been in touch to detail exactly what European owners should expect. As before, they're saying the 2.1 Eclair update should be out by the end of June: the first update, which is out this week, prepares the phone for the second, full OS upgrade.
That second upgrade will wipe the Hero completely, so HTC are recommending users back-up their handsets prior to installing it. Meanwhile it's also a sizeable package, so HTC recommend downloading it over WiFi rather than 3G.
"Android Éclair update for HTC Hero will be released by the end of June. The upgrade will come in two parts, the first of which will roll out from this week and will be detected when the Hero next automatically checks for software updates. The second part of the update will follow towards the end of the month. As the second part of the upgrade will wipe all data on the handset, Hero users should ensure any important data has been backed up before proceeding with the installation. Due to the size of the update, wherever possible, we would advise using a WiFi connection for this download to avoid additional data charges."
