looks promising, just very unstable. Crashed my e71s phone book repeaditly. Have trouble accessing my normal phone book at times. My suggestions (other than improving stability).
be able to change the font size of the messages. I felt that they were too large for teh screen and would of fit nicer with smaller font, or integrate it to take the phones font preference. Also to integrate it into messages as appose to phone book. I thought that was a horrible idea. i should be able to go to my messages and have all regular options like inbox outbox sent. but also have conversation in there. so u can utilize both methods. very helpful if it works smoothly. Please dont give up on it.
