Three, maybe basic, questions... I saw many people were reading the 4.2U update, around 420 I guess yesterday, and I came up with those questions: 1- I got a 3.4U and I want to update it to 4.2U but dont know if it is safe since I got an old firmware version installed. If it isn't safe is there anyway to update to 4.1U safely? 2- Do I really need to install the firmware update or installing the IOS the game needs works fine? 3- This is a very personal opinion... Should I stay on 3.4U, because it's saffer or something like that or should I try to update to a newer version like 4.1 4.2U? Thanks guys!
