thanks mate... I've been playing with the minimalistic text app alot lately, and the developer on XDA is awesome adding feature requests like TASKER integration... so my screen looks a bit different now
I got the HTC desire because it was the most powerful android phone available when I bought it and I'm increbibly happy with it unfortunately I don't understand what you mean, your english is rather bad or you were in a hurry when you typed this
Awesome, of course... I don't use appbrain although a similar site that I do use is www.androidpit.com but above all I'd check out XDA developers HTC Aria section available here, [link] you'll have to do a bit of reading but just check through there and you'll understand most of how to mod an Aria.
Good luck, if you have any more questions just ask
