GPS works just fine

I didn`t go anywhere, but as I see in TomTom, my position is accurate. I don`t know for sure... because I`m standing. Maybe if I go with my car, it will be problems with position, but as I see, it works fine (you know, that arrow it`s, in reality, like 3 blocks :)), so I don`t know, maybe it show that I`s 10 meter left/right, I don`t know). I will let you know in 2 hours, I must go now and check.

For me it worked just fine. I had iPad BASEBAND, iOS 5.1.1, jailbreak and hacktivation with "sn0wbreeze", unlock with "(edit)" and "ultrasn0w".
iPhone 3GS 16 GB

2. run as administrator "REDSN0W"-extras-SELECT IPSW (what IPSW YOU HAVE DOWNLOADED)
3. "slide to power off"
4. DFU (3 sec POWER, 10 sec POWER HOME, 10 sec HOME)

5. BACK in "redsn0w" -jailbreak-(leave Cydia marked) and mark "DOWNGRADE BASEBAND". NEXT!
