Hai guise

Just used iliberty to unlock/activate/jailbreak thanks to various threads and guides that have been stickied

theres so many sections on here my head is about to burst what would you advise me to do next. ie the most popular/neccessary things to install next

how exactly do i use the phone with my t-mobile contract now

yes a very broad question but any help please?

how do you use it with T-mobile ? Just simply insert your t-mobile sim card in it man. I am sure that wasn't what you were asking tho

Most necesaary things depend on what you want on your phone. There is nothing else you have to do right now. But if you are asking about must-have applications, then check the native apps subforum

if you are unlocked, just pop in the t-mobile sim and it will connect

Enjoy your iPhone

Like everyone else said, just pop in your SIM and go. If you have a data plan you will need to configure EDGE as well. To do this go to "Settings --> General --> Network --> EDGE" You will need to delete everything in there and put in internet2.voicestream.com or wap.voicestream.com. No username and password required. After that you should be good to go. Good luck!
