My first post here... but just wanted to say thanks for all the info on this thread. I've had my 770 for almost 2 years but only recently flashed it to 2007HE (same 4.2008.7-1 as Jorge used). Skype works excellent so far thanks to the step by step instructions posted here.

Just one small question. What files exactly does the cleanup stage mentioned above remove? I have not done this yet. What are the consequences of me not doing so?
