hey man... im a teenager too and i wouldnt be able to live without text messaging!! i have the sanyo scp-5500 (vm-4500) and its got camera and video and internet and everything and i dont have to go online to text message... some phones just dont have text message built in and i guess urs in one of them.. all of the newest sanyo phones and most of the samsung all have it built in.. so just upgrade your phone... u might wanna go to a sprint store or best buy so you can try one out and see. or just ask the guy lol... good luck!
