Almost all if not all Aifontriji being sold in LYP or Sg. Wang are US models. Hardware unlock may work but there are cases where calls need to be dialled twice and call dropping.

The best solution is still the fully unlocked ones. No cutting sim cards and planting them on dodgy sim plates, plus you're guaranteed future unlocked status even when Apple issues a firmware update. There are guarantees that the simulated AT&T hardware sims would prevent Apple from rendering it back into locked status.

Buying in the States no longer means waltzing into an Apple store and grabbing it off the shelf. You need Social Secuity number, which in turn will give them a valid American residential address and contact number. You will also be required to show proof of sufficient credit, via credit check with local American banks. Then only they will release ONE iPhone to you. Those planning to ask their uncles and aunties to get it will come back disappointed, unless your uncles and aunties are willing to sign off two years of their life on contract, not to mention RM6000 or more from their wallets. Enjoy!

Not to burst anyone's bubbles, but disallowment of IDA of any locked phone, may mean no locked phone TO a singular Singaporean carrier only. It may still be locked to the three Singaporean carriers.

Yup. all we have here are guesstimations. The same case was with the NZ iPhones , I wasnt even considering them until launch day, and the fact that the iFixit.com guys were lining up at the main Vodafone branch. What were a group of guys from the States doing there in NZ getting NZ iPhones, besides getting the first in the world?

Only through research on Geekzone forum, and confirmation from Cocklea that the unlocked status was a reality.

Why dont someone else do Singapore, just like how I did NZ? Research and info-finding can lead to satisfying results. Also remember, at the time of this post, iPhones from HK, NZ, Italy, Belgium, Switzerland and Australia are unlocked. Australia ones are unlocked with a request, while nobody knows the status on the European Aifontrijis. We all know about NZ ones.

Did your friend insert his own sim into the iPhone 3G? That would reveal if it indeed fully unlocked or if the seller has to mutilate his simcard to be slotted into the SIM-duping equipment.
