im looking to get an iphone in jan so im not familiar with it too much. my question is in regards to chat bubbles and themse for SMS etc. are you only relegated to the green chat bubbles or do you have customization over that? also are you able to have themse for SMS or no? if so do you have to jailbreak in order to get it to work or are you able to do so w/o jailbreaking the phone.
