During the past week, I have regularly been getting a "Flash Memory is Low" warning and the handset has generally been acting slowly, and particularly prevented me from accessing internet pages.

I have tried deleting a few unnecessary emails/photos and have altered the settings so that emails are only retained for 60 days (instead of 90) but so far to no avail.

Any idea what this means? It has been working fine since then but the red 'water damage' indicator is showing on the back of the device.

Thanks

Go into Options --> Status on the handheld, and what is the file free?
