X640 memory problem (Can't delete photos)

[Antori]

Hello,

First of all, I'm not sure if this is the correct subsection for this question, if it is not, I apologize for the inconvenience caused for the moderators/administrators.

Now to the question.

Let's bring in some background, was going to sell my X640 to a friend and wanted to clear everything from it first. So I took all the contacts away, all the messages (sms/mms), deleted all the photos on the phone and so forth.

The problem now is that some photos remain on the phone, but only when you go in to choose the wallpaper. If you go to photos or albums or anything it says there's no photos/images there. If you check the memory status it says that there's still stuff in the memory.

I looked at some of the photos that still remain and cannot be deleted, and they're all photos (i think) that I've received through messages (mms).

Is there any way to have these deleted? I don't care if it clears everything on the phone, as long as you can use the phone afterwards (that is, no changing IMEI numbers and such).

Second problem is that I don't have a data cable, and don't fancy buying one just so I can sell the phone, since I'm on a tight schedule (guy wants the phone), and that the cable would cost more than I get for the phone.

Oh, and as a last note, fast answers would be very much appreciated.
