i too noticed the rattle upon recieving my iphone 4s....
i have owned every single iphone and have not had this problem before....
my iphone 4 which i got on release day did not have this problem... **** it didnt even have a bad death grip problem. (slightly but not as bad as most)
i was disapointed but acceptable to the 3gs release....
i was disappointed even further in this latest release.... (hardware wise)
theres obviously something not quite right inside for it to have multiple rattle spots inside....
i called applecare about this....
they refered me to the mac genius' and upon ariving at the closest apple store, i felt blown off by the rep upon hearing my problem... ( i was also having a problem connecting calls ) the calls would connect but the line would be dead on my end. they could hear me i could no hear them, only an echo of myself...
FIRST time EVER in the last 7 years ive been dealing with apple's customer service had i ever felt this way and im willing to say that it was a fluke, perhaps other issues are factoring into why my latest experience went that way, ( it was extreamly busy that day ) maybe the rep i got was just having an off day or something.
so i called applecare back,
they agreed that i should just send in my phone to either have it repaired or replaced.
they chose to replace,
received the phone in 3 business days
and this phone rattles even worse than the last one!!!!
point being, if u can live with it, and its not that bad, get over it, and you'll forget about it before you know....
now my phone rattles obnoxiously loud, and what do i do now? send it in again?!
i think not....
i will wait for the redesigned iphone 5 and hopefully they will get it right this time...
