By the way about WP 8.1....
do we need to update it to lumia black in order to get wp8.1 in the near future?

Or im talking about 2 diff thing here... like firmware and OS...?? LOL im confused :/  kinda new to these stuff...

fixed

WP8.1 is a major update to WP8, just like what microsoft did to Windows 8 to Windows 8.1

OS = Operating System, like Windows 8,WP8

Firmware is the program code that stored inside the non-volatile memory of the electronics system, like Computer's BIOS.

Whenever Microsoft had new update for their OS, Microsoft will sent the patches to Nokia to do testing on their phones, and Nokia will bundle the patches with their firmware update to release to public to download.

For example:
In Lumia Amber firmware update, Microsoft release the patches that enable FM radio on their OS, able to sync google mail, adding data sense and etc.

But Nokia bundle the WP8 patches with their own firmware update as well, including ISO3200, camera algorithm improved, glance screen, double tap awake phone and etc.

So HTC and Samsung WP8 owner will only had features that found on the WP8 patches released by Microsoft unlocked, but can't enjoy the other features that Nokia included on their firmware update.

by the way i dont get why we need a setting for key vibration hahaaa
