Suggestion, try to search before you ask. Invest some time looking for apps and mods for your device. My first PPC I must have spent a minimum of 100 hours scouring the web on message boards and searches like "freeware for PPC" found tons of things many of which I no longer even use.
Just google SMS CHAT FOR PPC, first result.
