Hi! Just to let you know that the Tnt firmware rls 3 works perfectly on my Pipo M3 [I had the same problem as you with rls2]. And the 2GB internal memory is included. That kind of firmware is really improving my Pipo =).
Please a direct link for TNT rls 3 ?!
I have tried ver 3 "Pipo.M3.NON-3G.NEW-MOTHERBOARD. firmware_english_version12.22.2012" the 2Gb. not included !!!! (only 0.98 Gb.)
