I purchased a Galaxy SIII 32GB from PBTech, knowing it wouldn't be 2Degrees, so no Open SIMAlliance API for Touch2Pay.  Am currently on Vodafone (Hoping they are the other provider Snapper is working with currently).  Was just going to Use Odin to flash Vodafone or 2Degrees Firmware as I wanted.

Am perplexed with the Firmware that came with phone though.  When I put my brothers Touch2Pay SIM in it sees that fine and gives me the balance.  He can also check the balance with his SIII.  I didn't expect the App to be able to read it, expecting this to be an overseas phone without the capability.

My Phone

Product Code: GT-I9300MBONZC
PDA:  I9300XXALF2
Phone:  I9300XXLF2
CSC:  I9300NZCALF2

My Brothers SIII (16GB - 2 Degrees Stickered Box)

Product Code: GT-I9300MBDNZC
PDA:  I9300XXALF2
Phone:  I9300XXLF2
CSC:  I9300NZCALF2

The only difference between the two phones is the Product code, I have an O while he has a D.  Both are NZC which I guess is NZ Communications.

I am now thinking do I just leave as is or still chuck on the Vodafone, though I need to read up more about it I see that Cell Dormancy is talked about in other posts that 2D doesn't have it and Vodafone and Telecom do and this can reduce battery life.
