I look at the "How to check if you can unlock" thread. I bought the original Gevey Sim from Apple N Berry.
I have firmware 5.01 (preserved baseband upgrade). And 03.10.01. However, the Gevey method isnt working. How do I just upgrade the baseband to 04.10.01?

There is no way you can upgrade the baseband to 04.10.01
The only way you can upgrade your baseband is update to the latest iOS 5.1 which you should not do if you need the unlock.
What type of gevey sim do you have? Ultra? Pro?
On firmware 5.0 or above, the gevey unlock method is different. You have to go to settings/ Phone/ Sim application to turn on the "Acceppt" screen and "No Service" is actually like 1 signal bar before dial 112.

If you kept your SHSH blobs while you were on the lower versions (4.2.x and 4.3.x; you can check on Cydia which blobs have been saved). Then you can downgrade to iOS 4.3.3 by creating a custom firmware with iFaith. You will have baseband 04.10.01. Then finally upgrade to 5.0.1 (with a preserved baseband of 04.10.01).
*edit : that won't work.

OP you should check to see the gevey is working right and that you are doing the process correctly.

The frustrating part is that when you once run out of signals that is they go down to zero the gevey sim does not pick them up again you have to reboot the phone and reinsert the sim and do the instructions all over again. A pain for people who work on basements

it does work. i have gevey ultra bought from applenberry and iphone 4 iso 5.01 with bb 03.10.01 and with 1.02 furiousmod installed and it works perfectly. no problem whatsoever.
i suggest you try again the process. make sure you read/watch youtube video and follow instructions correctly.
