If you are going to use the softmod method, just follow it and it will provide what you need to update. The disk update suggestion was for if you were planning on using modchip only.
Did the softmod last night and it worked a treat! I did however have one issue and that was when I tried installing preloader which was included in the downloaded zip file off this site, for some reason it looked like it was trying to preform and upgrade to v4 even though the system was running v4.1e!
Anyway it doesn't look like its done any harm except the fact that I have some channels on the home page duplicated - how do I removes these? the news and the weather forecast channel only being the 2 that have dup.
I think I will install priiloader ......
