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
