If you buy the mod and the metal case you might as well also invest in the Mugen battery (eten.hu has 'em in stock again on 25 nov). I did this, and while it is quite an investment in the device (compared to e.g. a new Pandora or in 2009 the newer NIT) it does prolong the lifetime of the device.

Unfortunately I also just bought a microSD 8 GB, but oh well, mistakes happen.

I keep the original battery loaded at 40% to prolong it, and to have a reserve battery.

So, I am interested in buying the SD mod kit with the metal cover (in 1 time to cut the S&H costs) and once I have both will write my review here.
