I know its for the Nintendo DS and has been mentioned before, but Argos (in UK) are selling this
http://www.argos.co.uk/webapp/wcs/st...tId=1500243589
for £2.93, collect in store and if you are a member of Quidco you can get £1 back.
I've bought one and the 770 fits in great and I can also (just) fit my IGO bluetooth keyboard and a couple of memory cards (in cases) in as well, the stylii won't fit in the 770 slot but can be kept in the case

hope this helps

these are branded as "gameexpert" and HMV are doing them in their Sale at £4. argos are now about £6.

the case itself is black, zipped in two, and seems to me made from a very tough plastic which would give very good protection. Inside the case has 4 elastic straps which are fastened diagonaly across each corner.

The N800 fits very snugly, It is just a tiny bit big to slot straight in, but there is just enough give in the case for it to fit, once pushed home, and under the straps. It can then either be used in the case without access to the camera, stylus, or ports. You can also push the top of the 800 up, and have access to the ports. I reckon a N810 would fit fine, although the sliding keyboard would be an issue. My Igo Stowaway will not fit with or without the Nokia

The case comes with 3 spare DS styluses, a cleaning cloth, and a pair of screen protectors, which are too small for the Nokia. The package also has a "thumb stylus" which straps via velcro to your thumb. Did not seem very comfortable to me.
