Hi,
I don't know if this is related to developers having the ability to set different prices for different currencies / countries now? We received a noticed that we should do that on our paid app. I see I can set prices for different countries now on that app dashboard.
I'm on Verizon I see Need for Speed shift for $2.99 (I bought it during they're Christmas $.99 deal) kinda crummy not to get updates or be able to keep track of my purchase over my google account for my next phone. Then again for the price I paid I don't think I'll complain
Anyway, might have different prices if you're in different countries

I haven't seen any options to have different prices for different carriers, but then we're not as big as EA
