Assalamualaikum dan salam 1Malaysia.
Finally apple has come out with this update which supposely fix the batery life problems
As u know, now u dont need to plug in to itunes to update your idevice.
What u need is your idevice and a wifi spot. Go to setting>general>softwere update.
Scroll down and u will find download and install button, click in and for few moments..u can try the result.
But sadly in Sabah its hard dor me to find a stable wifi spot..so i might only update once i arrive in penang..sob sob..
So guys..enjoy the batery life saving(s apple ensure) and stay alert with ur idevice..it may need few other upgrade..lets find what it is
