I have a GSM iPhone 4 locked to Softbank in Japan that is unlocked with a Gevey Turbo SIM. It has baseband 04.10.01 and software version 5.0.1. I would like to upgrade to iOS 6 since there are more and more apps that won't work on iOS 5, but don't want to lose the ability to unlock with Gevey and would also like to maintain my jailbreak. I know Apple is no longer signing 6.1.2 IPSWs, but I've read there may be a way to downgrade from 6.1.3. I only have 6.1.3 and 5.x.x SHSH blobs saved with Cydia so this probably won't work leaving me with a tethered jailbreak. Does this sound correct? Any advice? Thanks!

Hello Brother, Sorry for replying late.
There are important things you need to know:
Unlock only depends on Baseband (firmware) not on ios.
And when we upgrade any IOS, baseband automatically gets updated.
BB 04.10.01 can be unlocked by Gevey Ultra (as you know)..but if you want to upgrade your IOS 5.0.1 to IOS 6.1.2, its BB also will be updated,and you will be not illegible to Unlock your phone in that scenario.
Hence I would like to let you know that please Preserve your BB and upgrade to new OS.
that you can do by redsnow (in mac and windows) and Snowbreeze (in windows only)...but as you know, that now Apple is not signing 6.1.2, 6.1.3 and 6.1.4.
So you have to wait for devTeam, ipod2g, evasion team to get a way to preserve baseband and upgrade to ios 7.
Once this update will be available, you can preserve Your BB and upgrade your IOS and you can unlock your iphone. But till then please don't upgrade your Iphone.
thanks. @Rukky_ind . sorry for my bad english
