I look Google, I look in “beta you than me”. But no one’s wrote what are the major improvements.

Just find this:
8700/8703/8705

• Spell check (H) • BlackBerry Maps with Points of Interest (H) • New pictures and ringtones applications (H) • Voice note recording (H) • Microsoft Office document editing with DocumentsToGo (H) • Native format attachment downloading (S) • HTML e-mails (S) • Over-the-air device upgrades (S) • Free/busy calendar lookup (S) • Searching the server for old e-mail messages (S)

Someone could help and if could post pictures even better.
