I have an iPhone 3G that I bought in the States along with an official at&t SIM.

My question is: Can I properly activate it while in another country?

I want start fresh and restore, re-unlock and re-jailbreak. I couldn't find a definitive answer anywhere.

I know that I can 'hacktivate,' however, I still want the ability for Push Notifications without the iffy 'fix.'

Thanks!
