I have V'fone/Samsung SGH-600 with removable/upgradeable microSD card (max 2GB)
These SIM sized cards can fit in USB adaptor to efectively make a memory stick for your PC/DTR as well.
Available Tesco's, Amazon and loads of other places. I recommend Sandisk stuff from Amazon based on price and I havent had any problems.
Just search something general in amazon like "2GB" and you will see loads of stuff.
I have a few 4GB and 8GB cards as well which I use for file transfers and backups.
Beware that some people report reliability issues (sudden failure) on many cards/sticks so have alternative backups.
They are cheap enough to throwaway, but of course data is valuable.
For the phone, if you dont have mem card you will need a USB cable to link to PC or Bluetooth whatever.
see samsung.com for transfer software for your phone. I use Samsung's "PC Studio". It's a heap of junk and often fails to connect or crashes. But it gets there with a little persistence.
For uploading by mem card/adaptor or mem stick to your Sagem DTR. I also have a Sagem DTR (64160T)
but have never tried USB transfers with it.
And judging by the amount of hassle reported on Digital Spy Forum/Sagem, I dont think I will bother.
As for your email printer problems, I cant help. Good luck.
