best exploit

Hello,

I'm new to this and have some questions:

I have a new Wii and want to install the homebrew channel. I have version 4.2E that is never updated.
I read the forum and the wiki and think i can use the bannerbomb exploit. Am i correct? Is this the best one to use for my version?

What SD card should i use? 2GB?
When i use now a 2GB card, and i want to move to a bigger one, is this possible? Do i only have to copy the files and disk structure to the new one?

When i use the guide posted on this forum, is everything then ok?

Allready thanks

1) Yes, you can use bannerbomb to install homebrew

2) Some Sd cards work great and others just don't, maybe your SD will work or maybe not. Just to make sure check this compatibility list. (If it is not listed don't worry, it doesn't mean that it will not work)

3) Of course you can use a bigger one, just check the compatibility list that I already mentioned

4) Copy the files with the same structure and there should be no problem

Hope that helps
