Yes this app solves the well known security problem of iPhone mail: anyone can read and send messages on tour behalf. However this app has some stability problems! At first use,when importing mail from mail server it may crash. I have competely solved this problem in the following way: 1) set to 25 the number of showed messages; 2) switchoff and restart. I find now the app very food and usable. No configuration problem as some users wrote. Everything is intuitive and easy. I just suggest to improve ( make more impressive ) the graphics of open messages. Moreover they have to solve those crash problems. My final vote is 3 stars. Just because I think this app is almost perfect and I whant to encourage the authors to finish their job. They have promised an updated version!!!
