it to 4.2.1, however i am confused? I have the baseband 05.13.04, which is already unlocked while i updated to 4.0, but thats so slow that i can have a cup of tea and come back by the time an application starts, heard 4.2.1 is fast but, can i directly update it to 4.2.1 without installing 4.1 first? Next thing is do I have to update the baseband or can i keep it to my current? help me please I am kinda stuck!!!!!
