Saved me posting it. You been away Melech? Welcome back

[Melech518]

Thanks man! Busy franchising our company. I am trying to get back on the forum more though.

Yup, worked perfect for me. T-Mobile US Prepaid!

Edit: So I have noticed that unless I turn FaceTime off in settings, my pre paid balance get charged 10cents every time I reboot my IPhone 4. I get a warning message about something like "Your carrier may charge MMS fees for connection to video calls" or something like that. Kinda sucks.

Awesome. Patience definitely pays off. People are definitely going to be happy.

This might sound newbie but is there a way to disable edge? Don't know if TMO will charge me like crazy.

FaceTime no longer works when unlocked. It says it's awaiting activation under the facetime slider.

[delusion950]

seen the unlock before you guys made the news. but it feels good having unlocked and jailbroken iphone !!!!

[sami4021]

Im getting "no sim". Suggestions? I cut it perfect and it fits perfectly

[moliko]

its working fine BUT:
1- face time is not working.
2- 3G network is enabled but not showing in the top bar.

any advice ?

[Melech518]

reset your network settings.

3G needs to be DISABLED on T-Mobile

[moliko]

reboot the device got 3G but still no face tim

Facetime working here.

[volcom2218]

Worked great on my iPhone 4, but after having AT&T for the first time I can't go back to EDGE speeds with T-Mobile.

Great job to everyone that made the unlock possible!

FaceTime is working for me. I don't know why I unlocked my i4 though lol. It's not like I'm gonna be using a different carrier.
