hi guys, i've got the the htc hero replaced with a 2nd one as the 1st one had reception issues. This 2nd one to be honest is slightly better, but still call quality is poor. Also i want to download loads of apps/games, but i'm limited as many end up installing on the internal memory, so i'm going to go for the custom rom mod. Now i don't have a single clue as to how to mod the htc to a custom firmware, so here are a few questions i want to ask:- 1. Is there some guide/tutorial available which i can follow to do the custom mod (i believe the best known rom is the modaco???)...can u provide me a link? 2. Other than the rom being faster, what other benefits can i get with it? 3. How can i replace this rom back with the orange rom if i want to go back to the original rom?
