how to flash with FZF rom? newbie

[Guest lionalcook]

hello all,

ive just got a mini pulse and had it unlocked - i put my network3 sim in and cant use any of the data things like skype or android market - ive checked all settings and i assume it wont work because its t-mobile firmware?

So...would flashing with the fzf rom cure this? - if so could any one be so kind as to post a step-by-step guide as i've been trying to get my head around this flashing thing (searching & researching for a couple of days now) and theres so many options I dont know the best one to take.

much appreciated.
