Over the weekend there was a newly leaked firmware version (1.21) for the Treo 650 that are supposed to address the infamous inefficiency use of RAM introduced with the new NVFS non-volatile flash memory system featured in the Tungsten T5 and the Treo 650. Even though it's still not an official release, I couldn't wait to give it a try. Oh boy does it work well! Even without putting apps in the ROM now I have 12MB of free RAM. One of the database that used to take up over 5MB now only shows up as less than 1MB! I don't know why engineers at PalmOne made the mistake with NVFS in the first place but this finally is what NVFS is supposed to be: a usable memory system that perserves your data even when your Treo runs out of power. I hope PalmOne releases an official version soon so I can create another custom ROM based on it and free up more RAM. Although at this point I am not complaining. Official or not, this 1.21 version works great!
