yeah so i'm getting the samsung gravity aqua and white t-mobile phone?

so, tell me who has this phone is it a good phone to use because in the past i had the samsung katalyst and it really didn't do much. Does this phone have more features and when i do get it, in order for the phone not to scratch where can i get the skins for that kind of phone

tell me if its a good phone to get?? because my contract was already done in December and i was thinking to switch to metro but the bill would be just the same so i would be staying with t-mobile
