massive black snow is not only black snow
its kind of all in one package ...... when u open it ...... u get blackrain ..... unlocker...... app sync 3.1 ..... custom firmware....... diskaid ...... touch .... n sum other option
1st download 3.1.2 custom firmware ........ n massive blacksn0w
go to itunes....... press shift n click restore...... click on custom firmware u downloaded n press ok n let it done ...... when done close itunes n dnt backup ur iphone
open massive black snow ......... 1st click blackrain ...... n rain it
then click unlocker n then app sync 3.1
thats it ....... enjoy ur jailbreaked n unlocked iphone
u dnt even need to install one free app from appstore to install other cracked apps
or here is alternative way but u need wifi access for this one
download n restore normal 3.1.2 formware
then download blackrain n rain it
u will get blackrain icon on ur iphone secreen
