Thanks to Joe Jerde and to his contribution of posting the leaked os 188.8.131.52 I could said now that I have a fully functional BB Bold 9900. the system is awsome and works 100 % . noticed a great performance in my equipment running 33 apps and still having 178mb free memory. the browser is more faster than 184.108.40.206, also gps is more accurate and waiting time after rebooting decrese noticely. once again thanks Joe.
If I may say (as an owner of a Bold 9900), a device's battery life has many deciding factors, such as what kind of apps, how many apps, do you close them off when not in use, which ones do you use most, and how long?
You can see how battery life is difficult to determine how long it would last with a new (leaked or official) OS release.
Try to use your BlackBerry device with just the bare minimum number of (native) apps, test that out for 1-3 days, then add one by one, to see what effect it has on the device's performance, and battery life in regards with OS220.127.116.11 for the BlackBerry Bold 9900.
If any member can post their experiences below, other BBOS members would be very appreciated.
