Are you one of those super nerds that think its okay to have your device start 
up with a BIOS gif? Well I am too, and I found this CAB laying around XDA, that I though you might be interested in. The image is nothing more than an animated GIF that brings up something similar to a BIOS page, but thankfully has some accurate information that other nerds like us might find cool.
The post has a BIOS page for the basic European HD2, and then an image for the more advanced T-mobileUSA version, with more things(okay guys, just pulling your strings.)
Well if your in the mode to try out a new look/startup on your Windows Phones… Then follow this link, and head over to XDA for the lowdown.
