I am a fan of any device that has a sick looking startup, so far Nexus One is on top, but this new startup is pretty high up also. The latest startup by XDA member gauravbaadshah, looks great, and embodies the four color of Windows, and either a Samsung, or HTC logo in the bottom. I cannot say much about it, but as you can see for your self, it looks pretty cool, and hopefully one day it will be animated.
UPDATE1 (18 June): WVGA for Samsung and HTC available now.
UPDATE2 (19 June): WQVGA for Samsung available now. All files are now available in cabs.
UPDATE3 (19 June): VGA for Dell added.
I made an amazing Welcomehead/Boot screen image consisting of HTC/Samsung and Windows phone logos . It is now available for QVGA, VGA, WQVGA and WVGA resolutions.
To install just copy the corresponding cab to your device and run it via any file explorer.
The following versions are available:
QVGA (240×320) HTC
VGA (480×640) HTC
VGA (480×640) Dell
