Hey guys, i have the first generation iphone and finally decided to upgrade to the 3gs........after doing much research on what case to get, i went with the switcheasy colors truffle and its still in its packaging awaiting the 3gs this coming week. My question is if this case gathers lint and dust which ends up scratching the apple logo and the back plastic? should i get the Zagg shield to go with the case? im a little unsure of the zagg but what do u guys think?
