HTC quietly announced an update to the HTC Flyer a couple of days ago quoting: “Improved System Performance“.  An improvement in speed is always a good thing!
Here’s what I got from the news feed:
Your Tablet will receive a notification of FOTA update when it is made available. Simply press OK to accept the update via a data connection such as Wi-Fi or GPRS/3G. After installing the update, you can confirm a successful update by confirming the Build number (From the Home Screen go to MENU> Settings> About Phone> Software Information> Software number). The new Build number after the update will be 2.00.405.3. Update: Improve system performance. Note:Please back up your data first before upgrading your phone. We recommend using a free Wi-Fi hotspot or an unlimited data plan to apply this update. If not, standard data connection charges may apply. For any questions, please contact us at http://www.htc.com/www/CA_Hotline.aspx
If you received the update, let us know if you’ve got improvements.
