HTC has just released a new ROM update for HTC Tattoo users on Orange. It is a manual update that must be downloaded and installed via a Windows-based computer using HTC Sync. The update takes about 10 minutes and will wipe your phone, so be sure to back up any important files first. Absent from their announcement is any detail on what exactly the new ROM updates, so any Tattoo on owners on Orange out there feel free to let us know what you think. Download and install instructions are here.
