I have wiped my device's OS and upgraded it to 4.5. One reason I wiped it was because of errors and looping in the Browser due
to Javascript errors which were caused by various unsupported or malware containing sites on the internet. Much to my suprise
wiping the device clean with JDE and updating with DM did not solve the Javascript Blackberry problems from before the wipe.
What remained on the device after the wipe persists with exactly the same sort of Javascript errors as before, all the Browser configs were renewed with the new OS in Options. Were the old Browser objects saved with the data and apps that got
backed up with DM and then restored after the wipe??? My Internet Browser works the same now as it did before the wipe of the
complete OS, with Javascript errors and a diagnostic that says Javascript is not supported even though the option is checked.
