    if your on the older bootrom then just restore to the custom 4.0 ipsw

    as you know, its been posted a million times, and its pretty much the same procedure as any ultrasn0w install, since last year.So i'll let you get creative and do a little research for yourself, instead of just spoon feeding you the answers.

    Hint: read the main page, read dev team blog, check out t-mobile section

    question is it safe to do the upgrade now or should I wait little bit more ?

    I suggest you wait a little bit longer when everything settles down. I managed to jailbreak and unlocked at iOS 4.0, but there are too many applications that don't work. For example, swiping sbsettings goes into safe mode, installing sbrotator makes Cydia dissappear..most of my Rocks Apps don't work...finally I decided to go back to 3.1.2 again..LOL
