No Service after updating to 5.0.1

I have a jailbroken iphone 3gs. Just upgraded from 3.1.3 to 5.0.1. When I turn my phone on, it says "no service" at the top. When I open cydia, it says I have SHSH: ios4.1, 5.0.1. I used redsn0w_win_0.9.10b1 to perform the upgrade. I had problems restoring to 5.0.1, so I unchecked the "set hosts to cydia on exit" in tiny umbrella and that took care of the restore issue. After using redsn0w, I went back and checked this box. I am still not getting any service, can anyone help me with this?

edit: I went into settings and turned off "enable 3g" and rebooted, still no service. Under settings>general>about, it says not available next to carrier.

I went back into cydia and installed untrasn0w 1.2.5. Now the services tab is stuck on "searching". Under settings>general>about, it says I am on the carrier "Carrier 11.0" and not T-Mobile like I think it should be.

Reset network settings.
Try a few reboot or reinstall ultrasnow.
You're sure you maintained your unlockable baseband from 3.1.3?

I reinstalled untrasnow and rebooted, no luck. Not sure what you mean by maintaning unlockable baseband? There was an error message that popped when I was reinstalling ultrasnow, "sub-process \bin\bzip 2 returned an error code (2)."

Edit: new error showing up when I added source "http://repo666.ultrasn0w.com", it says "GPG error BADSIG 694D17D38764B4F4 Big Boss

There were other error messages at the bottom, saying some indexes weren't installed.

Go to settings/general/about and tell me your modem firmware.
If you didnt save your baseband from 3.1.3 and updated to official 5.0.1 instead of custom 5.0.1 ipsw then your unlock is gone.

Modem Firmware 05.16.05. I used iphone 2,1_5.0.1_9A405_Resotore.
 
Yep, you messed up big this time.
You were not supposed to restore to official firmware.
That's why newbies should learn and ask questions first before they attempt anything they're not familiar with.
Now you lost your perfectly fine unlockable baseband.

Sorry to tell you this but you didn't preserve your baseband when you upgraded to 5.0.1 and now your unlock is gone. I think your only option now is to update to the ipad baseband 06.15.00. Downside to this is your GPS may not work and you will be stuck with this baseband.

is there a fix to this? I thought I was following the instructions I found at http://www.iclarified.com/entry/index.php?enid=18993, but must not have.

nope you are sol for now! no fix at this time no eta! hopefully somebody else will learn from your mistake.. I would strongly consider selling your phone and trying again or buy a t-mobil phone or go to att maybe the gophone option will work.

Those instructions are on how to perform an untethered jb as it says on the top of the page.
These are the instructions you were supposed to follow:
http://www.iclarified.com/entry/index.php?enid=18932
Ask questions first not after. If you mess up then you learn its too late now.
Only option now is the ipad bb and I dont advise that. Up to you.

Thanks for the advice, I wish I had gone there first. Why do you recommend not using the ipad bb? Is there a chance this bb issue will be reversible down the road? My iphone is just an extra phone I got from a relative, I still have my T-Mobile blackberry that I regularly use. If I don't try the ipad bb, the phone will just sit in a drawer.

And if anyone can direct me to a good site that explains how to do the ipad bb update, I would greatly appreciate it.

Because once you put ipad baseband onto your phone, you kill its GPS. Also, once it is on, there isn't a way to go back.
 
read everything about it before you do it. I really don't think it's a good solution why I didn't mention it. even though it is a solution for many.

in short

-Loss of GPS.
- in accurate signal strength.
- can not upgrade to official firmware gets annoying after some time.
- you lose your warranty because there is no way to downgrade so its clear to apple you have jailbroken device
- You can't downgrade you baseband.
-You will be stuck on the 6.15.00 baseband forever (or close to it!)

Is there a chance the error I made will be fixable in the near future? I am not worried about the warranty because it was a iphone 3gs my uncle got a year or two ago. It is just an extra phone I use when I am not using my blackberry. Am I better off waiting and letting the phone sit until my issue is fixable, or trying the ipad bb just so the phone is usable?

I wouldn't bet on a fix in the near future but anything is possible. Finding unlock exploits is very difficult. because there is very little code written.
 
can someone point me to a site to go to that can walk me through the process of updating to baseband 6.15.00? I have looked in a few spots, but nothing seems to work. My phone is still showing that I am on version 5.0.1 (9A405) and Modem Firmware 05.16.05 and am trying to make the phone work with T-Mobile.

Just use the same redsnow you used and go to jailbreak and then select "install ipad basebad".
