I am looking for an app to use for i/m instead of using the sms app. I am wanting to avoid the easy recovery of every text I send/receive. I know that given enough time that anything can be recovered, but I am only concerned with text. So, I hope that i/m will avoid this problem. Am I on the right track? If so, what works well? What will allow an icon on the main screen so I know when I have a message?
