Sony Ericsson S710a
Sony Ericsson Unlocked?
It's not that all Sony Ericsson Phones in the USA come unlocked. Rather, all the high end phones that Cingular releases have been known to be already unlocked when purchased from Cingular. I can say this from experience. My older brother purchased about 3 High end phones from Cingular when they were released, and they were all unlocked already. Also, I have spoken with other USA phoners on forums and they claim to have experienced the same with high end phones from Cingular. So to sum it up, 95% The S710a from cingular will be ulocked already and you'll be able to use any GSM service on it. 😎
That does not mean that the phone you get will definately be locked. Most of the shipments that I've seen since then were still unlocked. However it IS the policy now to lock them, so don't be suprised if you slip a T-Mo SIM card in and it doesn't work.
