i just bought this phone today its version is 1.1.2 and its firmware is 4.02.13 g

would it be easier to jailbreak in this version or should i install 1.1.4 like itunes asks

i used to have an iphone before so i know how to jailbreak it i just want to know if its possible with this phone since its not in 1.1.4 yet its in 1.1.2 but i dont want to do it if its going to mess things up
