Whenever I transfer files through bluetooth application ( i use IVt BluSoleil), the file is transfered to my messages inbox. So i cant transfer mp3s and videos because my phone memory is onlt about 3.8mb What should i do . i also cant move to a different folder. Any other bluetooth application or softwares offer to transfer files to specific locations on my 6600? Please help me.

You could change in Messaging the "Memory in use" setting from phone memory to the memory card. It moves the Inbox to the memory card.

Or you can use PC Suite's file transfer to copy files directly to the memory card.

Or you can use an USB card reader and copy the files to the memory card on your PC (and then put the card back in the phone).
