Here is my speculation on how the memory system actually works on the T300 (and on the T68 too probably)
The phone comes with 1MB total memory. From this 1MB a certain amount is already preloaded with pictures, ringtones MMS templates and incoming e-mail samples that were loaded with the flash firmware orignally.
So after a Master reset your only available memory is roughly 576K on a T300. The rest of it is already pre-occupied and there is nothing you can do about it.
However if you actually go into the my pictures you will see that at this point the pictures are not loaded into the phones dynamic memory, all you see is white blocks instead of pictures. However as soon as you start viewing them the phone copies these pictures from the preinstalled memory into the free memory area to display them.
Also if you have a theme installed and you activate it, it gets copied into another location, the current theme location. So even if you delete a theme when it's in use, the phone will alert you that the theme is in use but when you delete it, the theme will be gone and the memory that it occupied will be freed. However the memory where your currently selected theme resides is still occupied by the theme and this is why you can still use the theme even when it's been deleted from the phone. To verify this just download a theme to your phone then actuvate it. Then look at your memory usage. Then delete the theme while still active and look at your memory usage. It will be less. Then change back to the classic theme and the memory occupied will be even less.
Also the phone is pretty smart about not saving duplicates twice. So if you have a picture on the phone and then you end up sending it via MMS, it will be stored in your sent items folder as well as in the my pictures folder, but it will only take up real space once. But in the Memory data screen it will count it twice, once in the sent items and once in the pictures directory. So you can actually get the memory total up to even 1200K, if you send a ton of pictures via MMS as it will show the pictures in the sent items and in the pictures directory and it will count them twice. (beleive me, you didn't actually gain more memory it just looks like it) And this is when you delete a MMS mesage it will say freed 0, since the phone still need that picture for your pictures folder and could not really delete the picture all it deleted was the link to that picture from the sent MMS folder.
Also screensavers (animated gifs) are written so the first frame is saved as a full frame then the successive frames only store changes from the previous one (kind if like mpeg, but without compression). But for the phone to be able to animate it, it actually has to generate each successive frame as a whole so it will take up a lot more space when an animated gif is in use. This has been written down in the T300 white pages and MMS specifications......
And this is where the good things end and the issues begin.
1) why does the phone need to copy the preinstalled pictures from the already taken up memory space into the free memory when you open them and view them in the pictures list? This is a bug.
2) When you delete a picture it does not delete its "cached" version and it will not free up the memory that it occupied. (In essence each preinstalled picture ends up taking up twice its size as soon as you look at it even once, yet neither gets deleted when you remove it and I think at least the second copy should be deleted)
3) After a master reset the MMS templates are still stored in the phone wasting 111K but they are no longer available. So its written somewhere that the memory is occupied yet the links to the MMS templates are not restored in the MMS templates directory.
4) The phone should free up this cached memory locations as the images are not used from time to time to make room for more things. Once you look at a picture there is no way to free up its cached value.
I am pretty sure I'm right on the money with these assumptions (I am a software engineer working with complex data structures every day so I know some about how data is stored on systems), I just wish one of the SE morons who wrote this buggy POS would take a look over here, admit their problem and fix it ASAP!

@ GT, why not send your whole post to SE ? I doubt that they will read it here. Just send it to them direct.

I really don;t want to get innto it, but I have tried to contact them on so many different levels that it is not even human!
They just pooped on me and ignored my questions. I had no way of getting my problem through. The best they could tell me was to send my phone back to them and they will see what is wrong with it.
SE has been treated me like crap even after I've told them that they should listen to me and appreciate all the beta testing that I've done on their buggy phone. Bot NO, they just kept insisting that I'd have to send the phone back. They could not even tell me over the phone what the latest firmware version was that was available in the US service center for my phone. Bunch of morons if you ask me!
