After unlocking with ultrasnow do i have to use the gavey sim??
Or will my phone be able to work without gavey sim, on version5.1...
The gavey sim im using right now does'nt works on 5.1 from what i heard. That's why i wanted to ask if i should upgrade to 5.1 or not?

Tethered jailbreaked,
Contry india
I wAnt to upgrade to untethered 5.1 but im not sure if it will work with my gavey sim..
