With all the new beta codes, valid or otherwise, doing the rounds it has been hard to keep track of the best release. As of now the latest build seems to be 188.8.131.52 as we recently mentioned. Those that have installed OS 184.108.40.206 are reporting back that the release is quite stable compared to previous versions. Keep up the good work RIM!
There seems to be some doubt as to the authenticity of this release since it varies from the standard we are used to seeing in RIM betas. Meaning the software is designed for the BlackBerry but the code has been re-bundled as the screenshots shows below.
This includes the naming of the files found in some links, which are non standard. The comments on the installer state that this build was built by Inno Setup and not the normal Research In Motion and there is no formal File Version. I can only imagine that this was the result of extracted files that were then built into the beta we have now.
During the installation I noticed some changes in the Firmware code with regard to Theme selection. This lends weight to my assumption that this is a Beta/Internal release for RIM Testing. Or it could just be a fix of the ALX by those that rebuilt this release, and the all famous Quincy (Removal), Celldata and (an application I have never seen before) Battery Log. These are packaged into an Internal Apps installation that comes along with this OS.
The installation seemed to be a standard install, nothing different other than the few extras mentioned where you can choose which vendor theme to install.
Starting up after the upgrade was very long, 24 Minutes, with the battery pull startup being quicker at times and other times not. Overall not much difference noticed, 2 1/2 to 3 minutes seemed normal to be the normal average for a reboot.
The internet browsing and overall handheld performance actually seems improved. The browser looks like it does a fetch of the page and then load of of the page quite quickly. Given that the device in this case is on a BES running 4.1.5, there maybe some further performance gains with MDS.
The handheld performance overall is very stable compared to previous releases. Hopefully with further tweaking of what is installed and running on the Device this will continue to improve.
