I returned it, customer service is horrible, he treated me like I wanted to cause problem to them.
he said this is NOT a known issue to iPad (i thought it's supposed to be known issue, and for a known issue, users have to live with); and kept rushing me to point my finger on an e-agreement for replacement one with carton box (not a retail box one), no more refund, no more replacement ... WTH, i bought it within 14 days ...
without Steve, iPad seems to have more problems than before. Apple should be aware of that ...
so far new iPad has : overheating, backlight leakage/bleeding and wifi problem ... sigh ...
