Not a Blackberry yet.
Idea is quite good but software is quite buggy.
1. A lot of problems with code pages. Very frequently e-mails are looking like encrypted messages.
2. Awfully search capabilities.
3. Calendar is not integrated with iOS calendar (the biggest problem for me) so it is impossible to see personal and corporate events on single screen.
4. Complicated workflow with attachments.
5. Usability is incomparable with iOS (apple) usability. I used GFE on iPhone and on iPad. On iPhone I removed this app after 1 hour; on iPad Im using it, experience is incomparable with native iOS mail client.
