No GPS on 3gs

[Iphonedummy]

My GPS has not worked since I upgraded the phone to 4.3.3, from 4.1.

It has been jailbroken with Ultrasn0w, latest version and unlocked using Sn0wbreeze.

I have a 3GS old bootrom, old phone.
I am currently running 5.1.1.
I have a BB of 05.13.04, which I thought was good to keep it from my reading on various forums.
Have never updated the baseband. Could this be the reason my GPS does not work.

Is there a process to follow, that gets my GPS working again? --- Flashing baseband?-How? --- Cydia fix?

Thanks for any help

Try flashing your baseband to the iPad 06.15.00 baseband, then downgrade it back down to the 05.13.04 baseband. That's one of the easier way to fix the GPS issue for good. There were a few GPS fixers in Cydia but they eventually faded out because they weren't updated and it was only temporary.

Still no GPS,
I have now even flashed baseband to the Ipad BB, and then back down to 5.13.04

Any other ideas?

Maybe it is hardware, I also have opened it up and checked the connection, but again. No GPS

Are their any apps that run GPS diagnostics, or something like this to check if it is the chip or the antenna?

Thanks again
