Text Message App. for BlackBerry?

I have a blacberry curve.. and i was wondering if there is any cool applications for text message. i noticed that the G1 has chomp sms and i would love something like that. I think the iphone has the same thing. it has all da message in one box from one person and each message is a bubble. please help me find one and if their isn't any out there then RIM needs to make one! lol I tried using message peak on BB [trial] but i needed a register code that i didnt know where to find but i dont think its what im looking for.
