Here's a sneak peak at Windows Mobile 5 successor, Crossbow. What would you do when posting an exclusive of a highly anticipated OS...go through every IM sound effect known to man you say? Then today is your lucky day.
It doesn't look like much has changed.
God I hope things have changed... Mobile 5 has been so buggy almost everyone I know who has gotten a device with it on it has returned it for a Palm OS device, or one a previous version of Windows mobile OS.
