Spec differences between T103,4, and 5?

[DroidUser3.0]

So I've searched and have come up short on any real info as to how these models were upgraded from their release versions.

Anyone have any more info? Thoughts?

As far as I know, the hardware specs on all three are exactly the same and only signify what retail outlet they came from. The only difference that I've been able to discover is that the T104 comes with two (2) 8 GB SD cards and the T103/105 come with one (1) 8 GB SD and one (1) 4GB SD card instead.
