I have been using my 1st generation iPhone with T-mobile for months now and I've loved it. Recently a friend gave me their iPhone 3gs which is a big upgrade and I want to use it with my T-mobile prepaid account. The process was so surprisingly easy with the iPhone 2g. Now with the 3Gs it's been a nightmare. I need to know what I'm doing wrong:
-I jailbroke my phone with the most current Redsn0w software for mac OS.
-I then unlocked it using ultrasn0w on my iPhone.
-Then I updated the Network settings for T-mobile with these settings:
MMS Proxy: 220.127.116.11:8080
MMS Max Message Size: 1048576
MMS UA Prof URL: http://www.apple.com/mms/uaprof.rdf
Still my iPhone says "Searching..." I have yet to see it say "T-mobile" or been able to use the phone.

You probably need a data plan with the 3GS. I have seen these run on Simple Mobile and H20. Good luck!

You do NOT need a monthly subscription. Nobody here has even asked you what baseband firmware you have. If your baseband is a newer version that is unsupported by ultrasn0w, then you simply cannot soft-unlock. If that is the case, you MUST purchase a Gevey SIM adapter for your iPhone. I've been using t-mobile prepaid on the iPhone 2G, 3G, 3GS, and now iPhone 4, for over 3 years. I've worked with my fair share of devices and the only instance where a prepaid SIM couldn't be used on an iPhone was when the SIM slot pins were scraped off by the SIM tray.

Ok so I have a Iphone 3gs that I am going to unlock. I have the proper baseband and know I can do it but my question is is there anyway to know that it worked for sure without an active tmobile sim? i have an unactive tmobile prepaid sim but I dont want to activate it until I know im good to go.. so if i put the sim in the phone after its unlocked can i look in settings to check just to make sure its reading it? thanks guys
edit:why am i up this early? 130am eastern
