Hi,
Im new in this forum and as every noob I dont understand a lot of things and cant find answers...Thats why I would like to ask you for help.
I have made jaibreak (or I think so - it shows me "you are jailbroken").
My problem is:
1. When i connect device to pc(win 7) i cant see all folders (including system folders), just main folder "documents". What do I have to do to see full device in PC?
2. Does it exist something like file manager in kindle, where I can see and browse my folders in device?
3.Do I need SSH to change fonts and install GUI launcher, because I totally dont understand what SSH is and I dont wont to mess with it if it is not necessary.

I would really apreciate your help.
Thank you
