I've edit my post to clarify a bit a few bits. I meant the quick launch *bar (just googled the correct wording), not really a menu.

To my knowledge, previously in order to pull up the quick launch bar, you had to perform a slighty complicated swipe, which wasn't always responsive for me in PR1.2 (so I never used it):
"by swiping up from the bottom of the screen and holding briefly" as quoted from swipe.nokia.com/design
But in PR1.3, all I've done were quick flicks on the Lock Screen, and the quick launch bar always appears when I go bottom-up no matter how fast I swipe.

ya exactly , you are damn right!!!!
on PR 1.2 , a fast swipe from bottom to top would inlock the screen ,
but now it opens quick launch bar,

using 3G internet doesn’t heat Up battery , or else on PR 1.2 i have experinced device heat up after long usage of 3G internet

My N9 with PR 1.3 is still easy to unlock from bottom to top with a fast swipe Also easier for me to open quick launch bar

bhai you are not getting my point!!!!

wat am saying is earlier(PR1.2) opening quick launch bar was bit sensitive!!!!
but now(PR1.3) its damn easy!!!!!!
