You can check out this app Groups: SMS, Mail and Manage Contacts Groups: SMS, Mail and Manage Contacts for iPhone, iPod touch, and iPad on the iTunes App Store .

If you don't need the user to stay within the app you can just use the URL scheme for opening the mail or SMS app. The benefit is the UI the user is familiar with will be displayed and almost for free development-wise.
