sending service books, will get your email, web and any service that needs data working. Re sending them is easy you just need to visit the bis website for your carrier or call them up and they can re send them too.
Or you can send them to yourself via the "email setup wizard" on your device: email setup>browser opens, page loads scroll to "help">page refreshes, select send service books>page refreshes et voila, you can close... Sending service books can also restore missing icons for data related services and apps, ie. BBM, Browser, Appworld etc... Cheers!
