The only problem that bother me is the inner ring for the d pad is peeling off.. So sakit mata when it glow at night. got light leaking from it. I'm gonna upload the pic later.. Other than that, I don't have any problem with this phone yet. I'm hoping it never will.. 

Is San disk 2Gb M2 compatible with this phone? does the phone lag when the M2 is nearly full? I'm planning to buy it la. Currently using 128mb M2

harlo i also got my phone like 4 days ago lol

anyway to questions, hope i can help

1. to unlock without sliding it open , press UNLOCK (left button) and OK (irght button)

2. YES u can change colors to set on ur ringing tone default , on ur contact ringtone to differentiate who is calling you by colors or as a silent mode u can use lights instead of vibrates
GO TO SETTINGS , THE GO TO SOUNDS AND ALERTS then GO TO LIGHTS EFFECTS
as for contact ringtone , u can CHANGE IT by individually by going to ur CONTACT and EDIT
IF u are asking about the lights which u slide down that can't be changed ( i think so ) unless the themes are changed
u cannot set the colors of that only if ur themes are different then the color in default will be different

3.ermm, ofcourse u can open the slot to take out ur memory card, but preferably off ur phone first lor then only take it out.It is new that is y is tight lor

Hope i answer correctly as im using it lor

i tried w910i at sony center but feel that it's a little bit big... maybe because i use to play w580i always... =p

well i will go for w580i because i like the color n the function.. at least now my frens around no one G with me.. so 3G function not very useful for me actually..

but still have long long way to go to have enough money to buy this phone T.T when only nx batch SE phone release so that w580i will drop price huh? >.<
