C600: Not enough memory for message downloading

[Guest petec500]

My wife has just sent me an MMS but when i try to download it, i first get the error message:

"Unable to receive your message(s). Your message(s) notification(s) will remain in the Inbox"

Then i get:

"There is not enough free space for message downloading. Please free up some space and try again"

I've only got 8 messages in my inbox so i guess the problem isnt there.

Any ideas how i find out what's taking up all my memory so i can free up space?

What about emails, SMS ?

Ringtones, homescreens, anything else in My Documents on the phone itself ?

Software installed on the phone rather than the storage card ?

Check your Sent Items and Deleted Items folder?

My phone was showing:

Storage memory - Used 13.34MB - Free 3.61MB

I then deleted all my SMS text messages (received, sent & deleted - i had no emails) and got to:

Storage memory - Used 12.87MB - Free 4.08MB

So i'd freed up 47KB of data, which did then allow me to download the MMS, which was 66k in size.

The thing is though, why did i have to do this when i still had 3.61MB of free storage space?

Also, the Program Memory is showing as - Used 19.67 - Free 25.39MB

Is there any way of changing the allocation of free memory from program to storage?

I really cant see anything else on the phone that's taking up all my storage memory (very few ringtones, no homescreens). All my files are kept on the storage card. I only have one small program loaded too.

Finally, how can i save photos sent via MMS to the storage card?
