I read rumors and reports dating from mid-July about iPhone 4 now being manufactured and shipped with a coating on the antenna (thus eliminating signal loss). I haven't heard anything recently about it and the signal issues are the main reason i have not bought one already (i have a 3g). I'm also a lefty so if anyone can confirm, or deny this, that would be greatly appreciated. (Apple won't tell me, and ATT doesnt know..)
