Where is the 'i'nformation sound?!

[Guest Em]

My smartphone (WM5.0 - i-mate Smartflip) decided of its own accord* to change the sound you get for events such as 'i'nformation - and that appears to be quite widely used (eg. also for confirmation fo SMS send, etc).

It's now that annoying 'doink' system sound. It used to be one of the normal .wav sounds that is used for questions, etc (a sort of 'di-di-ding'**).

But in HKCU there is no Information sound or anythign I can find like it.

Any idea where this sound is held??

* Oh ok, I fiddle all the time and install stuff lots, so maybe I broke it. :D

** And don't you just love tryign to describe sounds in writing?! :)
