right now 90% of all bent iPhones are macrumor users and there are 5 of those who have actually posted pictures and 2 are likely and rest were drive by trolling. so say 10 million iPhones were shipped, 6 million were delivered. lets do 12 users , so 12 users of 6 million is 0.0002%. now that is those who have come out.
lets assume that there are 3000 users instead of 12 users, that would make it 0.05%
Now lets assume even further there are 30,000 users with this, that would make it 0.5%
now lets take it further and make it 300,000 users with this, that would make it 5% and match a typical product failure rate of 4-8%, that is the industry standard.
Now do you think if there were 300,000 users with this issue. they would be venting somewhere online in the age of macrumors, twitter, facebook google plus, vimeo....ANYWHERE? no.
