I would like to upgrade to 5.0.1 and would like to ask for some assistance.. Last time I upgraded to ios 5 and didnt realise that it would change the baseband. So I want to update because I have heard there are some bug fixes in the 5.0.1 for battery life and stuff.. I read in some sites that it is possible to do so via redsnow to create a custom firmware to perserve the baseband. Is that true? Does it work??

Will appreaciate if you help me out..
