M218B upgrade from A+ successful! So for those who want the entire process: jetBook 33g --> A+ v. 27 --> B v. 44. I used a hard reset after each firmware upgrade and NO reset to defaults.
However, I'm not really seeing much difference between A+ and B other than the wireless settings. Since the jetBook does not have wireless, it freezes whenever you try to access those parts of the system. There is an "execute file" option in the file manager which leaves me wondering...
So you get SWF... anything else?
Custom fonts and more PDF options will keep me hooked either way, I think.
