Very true, even with this problem people will continue buying as many iPhone 4s as Apple can make. People want the device enough to put up with AT&T's limited coverage, poor reliability, high contract cost, and now a phone that has problems if you touch it the wrong way. Plus any true Apple fan will just buy the bumper case to fix this.
AT&T works good down here in Miami, I never drop or loose bars. Where I live way west of the city (nearly in swampland lol) AT&T is the only provider that has coverage. Everywhere I have gone in Florida from Miami to Tampa to Orlando has had good coverage on my phone. Then again, I don't use an iPhone lol
