guys,i jus get an iphone 4 from maxis(outright purchase from some forumer)

my home button is loosening/rattles its like when u place ur finger on the button(not pressing on it) and move slightly 4 direction
its a bit loose and wiggles back and forth , it's possible to move the button around without pressing it down. its really annoy me!

i did try to ask maxis for dis problem,they said its replaceable..

but the problem is im having dificulty for the warranty method since the phone is not register with me,lets say even i am able to get the phone warranty im worry the actual owner will be contacted and runaway with my phone

i got frens who specialise in repair handphone including ip4 , should i let them open up and fix the problem(which will void the warranty apparently)
or um...is there any other way?

i been headache for dis problem quite a while  , i would greatly appreciate for any recommendation and suggestion from any frens here...
i am out of idea for now,imagine spending 2.45k for a problem phone , pls help me out

i not really asking for the owner perhaps it will be better if he dont noe...i worry during warranty done they usually refer to the phone register to whos number during outright purchase and contact back him not me  and runaway with it...
somehow wad u said is reasonable....some fren sstilll telling me jus forgot it and enjoy the great phone 
jus im annoying , pay a high price for an un-perfect

For those who currently having problems with the home button, just use "Activator" as a temporary solution. At least you won't having the hard time to press the problematic button till you send it for repair.

wah,i thought they give the new one,not refurbished,haiyaa ..

Mine also hav the same problem.. Volume buttons loose & rattling sounds when u press/touch. Not sure is common issue or not. Should goto DiGi for replacement/repair? Any idea or anyone had successfully got replacement unit regarding this issue???
