To answer all of you in one go:
I will release the HTC theme once I'm happy with it and I deem it ready; by this time I hope to have got in touch with the weather icon designer. Though I'm not new to web design, I am new to Winterboard / iOS theming and also the Jailbreak community. I want to find the best way to distribute my theme and am open to suggestions.
My whole theme is actually a compiled, customised version of Suave HD. Get yourself Five Column SB, Five Icon Switcher, Clock Hide and Gridlock and you're well on your way. The rest is taken from Glasklart HD and the Wi-Fi/Signal bars on page 112 of this thread.
Didn't realise how popular it would be! I made it for myself
