Ok do this....go to add and remove and remove all the OS installs on the computer. Make sure there is no OS in C:\Program Files\Common Files\Research In Motion\Shared\Loader Files. Should be empty once you deleted it in add and remove. Than Re-run the installer and delete the vendor.xml and than hit loader again.
OK Findngs for Platform 18.104.22.168, App Version 22.214.171.124 (172)
these are based on changes from 3.5 (IMO) but remember you most likly need to give it time to settle in
Now i've only had it on for 15 minutes and did 1 battery pull after upload just to jump start it.
Accelerometer slower and clock coming up more often on app opening
typing just as fast and smooth
full querty in portrait
cut and paste works great
Camera actually a little quicker
video works fine
On both the above it is fixed if you rename and same (no flickering)
apps open and load just as fast as 3.5
Phone working fine, keyboards all good.
Memory still starting about the same on mine 41.5, Isee no difference.
Ask me some questions, but in my opinion I wouldnt spend the time to upgrade if you are not having any issues with 3.5, .122 nothing bad just dont see anything thats better
