Let me aplogize in advance for my ignorance, but how do you install this sandisk into my 8830. I took the batterpack off and see where to insert this sandisk but it doesn't seem to fit correctly? Please help. Thanks

Don't know about the physical size of the card but the 4.2 OS only works with cards up to 4 GB. Read somewhere that 4.3 will go up to 6.

You have to slide it into the metal bracket first then close it.

I read that 4.3.x will support 8gb, but is it available for the 8820?

It depends on the OS you have on your device.
