I am currently running Ios 4.1 on baseband 2.10.04. I am planning to upgrade to Ios 5.1 while preserving my baseband. I did some research online and found out that I will lose my Gevey unlock if I update to 5.1 on baseband 2.10.04. If anyone is running it successfully can you please let me know. I have no SSH saved so I can't upgrade to 5.0.1 which I think works with Gevey sim.
