A few days ago Arne released ROM version 1.50.8.6 on PPCW.Net for owners of his i-Mate Smartphone devices.
"The new ROM is a major improvement for the overall stability of your device so it is highly recommended to upgrade your Smartphone. However, please take the time to do it carefully."
While this is specifically for i-Mate owners, it seems to work on all SPV and Tanager devices. Of course, if you aren't an i-Mate owner you should be very cautious with doing this since it ROM flashing has the potential to turn your device into a useless brick if not done correctly. Personally, I plan to try this on my Tanager as soon as I get everything backed up. With this, I might
finally be able to get my Eleksen keyboard to work.
