My dad is on t-mobile and really wanted an iphone. So he bought himself a 3gs and gave it to me to jail break. I just want some help to make sure I can get it on the most up to date iOS and have it untethered as he would have no idea how to run the phone in tethered mode. So what I have about the phone so far is

Serial # 87944xxxxxxxx
Modem firmware 05.16.02
Version 4.3.5 (8L1)
bootrom is 359.3.2

I have it jailbroken and tethered at this point. But I really would like to see if I could get it untethered. When i ran redsnow it asked me about updating the ipad setting or whatever, but i didn't as of yet. Any help would be greatly appreciated.

The only way you can unlock that phone is to upgrade the baseband to 06.15.00, which will impact your ability to complete a normal restore, stop your GPS from working, and void the device's warranty. If you still want to do it, here's what you'd need to do:

1) Upgrade the device to iOS 5.0.1 through iTunes normally.
2) Use redsn0w 0.9.10b5 and tell it to install the iPad baseband. DO NOT INSTALL CYDIA AT THE SAME TIME OR redsn0w WILL CRASH. UNCHECK INSTALL CYDIA FOR THIS!
3) When the iPad baseband flash completes, re-run redsn0w and choose to Install Cydia.
4) When redsn0w completes, open Cydia and install ultrasn0w.

OPTIONAL: To generate legitimate push certificates for push notifications / iMessage / Facetime activation
1) In Cydia, add repo.bingner.com
2) Install SAM and SAMPrefs from Cydia
3) Open SAMPrefs and select 'Revert lockdownd to stock', then select 'De-activate'.
4) Reboot the iPhone.
5) Plug the iPhone into iTunes when it reboots.
6) After sync, download 'iPusher' from the App Store (free) and use it to test push notifications.
7) If activation fails, open SAMPrefs and manually configure the Carrier and SIM instead of leaving at 'Automatic', then repeat steps 4 to 6.

OPTIONAL: To fix MMS sending/receiving (To alleviate the size restriction error message)
1) Use a Cydia app or other program to allow you APN editing access. (I use TetherMe APN since I bought TetherMe, but there are others)
2) Set the following settings in your APN settings:

Code:

Cellular Data
APN: epc.tmoble.com
Username: leave blank
Password: leave blank

MMS
APN: epc.tmobile.com
Username: leave blank
Password: leave blank
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Proxy: 216.155.165.50:8080
MMS Max Message Size: 1048576
MMS UA Prof URL: http://www.apple.com/mms/uaprof.rdf

3) Download a .plist editor and use an AFC browser (iFunBox/DiskAid/iPhoneBrowser) or SSH to open /Library/Preferences/com.apple.mms_override.plist and replace the contents with:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

3) Reboot the phone and then test MMS.

It's important to note that if you want iMessage and FaceTime to activate against the T-Mobile phone number (and not just the Apple ID's e-mail address) the phone MUST be able to send SMS to an international number, as it will send one or two SMS messages in order to complete the activation. This is not 'blocked' by default, however, pay as you go plans must have additional credit on the account for the SMS to successfully transmit.

So i got it working. Thank you very much for the outline. I did the Sam and Sam pref and push notifications work.
I don't know how to do the MMS stuff that you suggested. I tried this video on youtube:

How To Get MMS On iPhone 4/3Gs/3G/2G Tmobile - Any Firmware! 5.0.1/5.0/4.3.5/4.2.1/3.1.3 + Data! - YouTube

I did that before I did the SAM Pref stuff and mms worked and now mms doesn't seem to work after doing the SAM push notifcations. I have the screen to put in the APN settings but I don't understand how to do any of the next step. *** Update I have got the plist editor pro and iphone browser but I can't locate the file you mentioned to edit (/Library/Preferences/com.apple.mms_override.plist. Is that because i ran the mms fix thing from the youtube video?

TDenn

*****UPDATE***I uninstalled the t-mobile fix from the youtube video and still don't see the file "com.apple.mms_override.plist" Any thoughts? Do i just create one?

Surprised that it doesn't exist, I think it is only on iOS 5.0+. In any case, you can cut the entire text and create the file. You should be good to go after a reboot.

I got another 3gs and was attempting to jail break it. Thinking I did one before I would just follow the same procedure as last time. So i got it, updated to 5.0.1 using itunes.

Firmware is now 06.15.00
Bootrom is the new 3.2
Serial number is xx944

Upon opening redsn0w i ran jailbreak and did just the ipad baseband update. That worked just fine. Then i went to rerun redsn0w and jailbreak with cydia. I have tried to do it with both "cydia" and baseband checked. Also did it with just cydia. I gave the same error which is the following:

lwvm::_partitionsfromconfig - loaded congifuration for 2 partitions
Mounting rootfs as read-only...
ERROR!
AppleBCMWLANCore::handleIOKitBusyWatchdogTimeout() : Error, no successful firmware download after 60000ms!! Giving up...

Any ideas?

Are you sure that the baseband in the phone is functional? That error pretty much means that iTunes was trying to talk to the baseband and the baseband wasn't responding. This can happen if you're restoring an .IPSW that has a baseband update included (since you're 06.15.00 this won't work).

I would try and re-flash the ipad baseband from redsn0w (do not check Cydia at the same time!!!) and see if you were successful.

It was not jailbroken or unlocked before. Is that going to matter? When I got the phone, I did basically the same as before. Connected to itunes and upgraded to 5.0.1. Then opened redsn0w; did baseband update; then attempted to do the cydia install. Again it was not jailbroken before. Please tell me i didn't botch this. I'm attempting the flash now. Will update in a bit on how it went.

***Update. Tried to redo the baseband flash and got the same error. Was it do it not being unlocked before?

So I finally got it to jailbreak. Not sure what I did differeently but i'll take it. I'm on this part again. Question in regards to:

/Library/Preferences/com.apple.mms_override.plist

This one doesn't have the file again. In the preferences i have "com.apple.captive.plist". Within the preference there is another file 'System Configuration' and inside it there is:

networkinterfaces.plist
com.appl.autowake.plist
com.applepowermanagement.plist
com.apple.mobilegestalt.plist
com.apple.network.identification.plist
com.apple.radios.plist
com.apple.wifi.plist
preferences.plist

Which is the exact location to create that file and add the info that you mentioned n1ck? Thanks so much for your help!

*update i was using a program called "plist editor pro" to try and create the file. I would appear as if it made the file but it didn't save what I put in. Any other plist programs?

Check /var/mobile/Library/Preferences/com.apple.mms_override.plist
