They should also let the user choose to mine in a pool, instead of forcing solo-mining.
There's software for that; Crazyguy's firmware allows you to use the 5 GH/S on a pool of your choice. I'll link it to you later if you're interested, but I don't really remember where it was located.
Pretty neat stuff, also fixed the U3 Zombie issue. It's not the best miner for its price anyways, and unless you're using the outdated U3 or the Gekko Compacs on them, it's worthless, at least to me.
