How to upgrade baseband

[maximedelo]

Hi, I have an Iphone 4 with baseband 02.10.04 on IOS5. it seems to cause me some problems. Battery drain, heating and no GPS. I would like to upgrade baseband to 04.10.01, which should solve the problem that I read... Any possibilities??? I am using Gevey SIM Ultra so that's why I cant do a regular upgrade.


Thanks

02.10.04 is newer than 04.10.01 so that would be downgrading which is not possible. Also, baseband version would not cause the issues you are describing.
