iPhone 4 -- 01.59.00 / 4.1 -- no service
I finally got my hands on an iPhone 4 running firmware 4.1 / baseband 01.59.00, and the person using it prior to me was using t-mobile. They had deleted their data via syncing "everything" to a blank iTunes.
I cut my simcard tonight and when I put it into the phone I am not able to get any signal. I am really scared to mess around with this too much as I just paid a bunch of money for an unlocked iPhone 4 to finally use it with t-mobile.
Could anyone advise me on what steps I should take to try and make sure everything is set up properly for the unlock to be working?
Thanks, greatly appreciate any help!!!

Good to hear it worked out for you, this was my problem too when i received my iphone 4 with 4.0 1.59.00 bb, using t-mobile. I found after i updated to 4.2.1 the problem rarely happens for me when rebooting now.

Is that an easy update?
I am terrified to update anything as I don't want to mess up the unlock =X

Extremely easy in fact, I created a custom firmware with sn0wbreeze which removes the baseband update from the offical firmware.
You can also use Tinyumbrella to update with official firmware by running TSS server to block baseband updating through itunes.
Both methods work. Just remember to save your shsh blobs through TU in case you ever wanted to restore back to 4.1.

Everything went great, except I cannot figure out how to do this:
"download SAM from cydia later and use it to de-activate the hactivation on the iphone so that you can use your at&t sim card to activate officially"
As I cannot find SAM in cydia.
but everything seems to be working properly, well Edge at leas, i don't think my phone plan allows MMS anyhow!

Why would I do this necessarily?
Everything seems to be working just fine on my iPhone, if this is the case, should I still do this?

If your push notifications are working and so is the youtube.app then you don't really need to install SAM. only suggested it because you planned on using the hackivation which can cause push notifications issues.
