Services Mobile for iOS version 4.5 comes with a redesigned profile and some bug fixes. Here are the release notes:
These update notes aren’t like you know ’em, these are phrased, each one a poem.
Your profile has a new design, that shows you much more at a time.
Positions needed were not syncing, now that’s fixed our bugs are shrinking!
Bettered push notifications, they’ll always come, what a sensation!
In order to fix push notifications, we had to make some changes in the app and on our push notification servers. Until you update to this version, you will now get double push notifications for emails if you've recently opened the app.
