Latin American phone working in the US?

[alockwood]

Hi. This might be a tricky question. Here it goes!

I bought a Samsung Galaxy Ace in latin america ( S5830L ), but I'm moving to the US (Minnesota). Will my phone work there?

It's unlocked for all the operators (cellphone service providers) in Venezuela (although with one of them, it doesn't get 3G). That makes 3, knows as Movistar, Movilnet, and Digitel.

Since it's a GSM phone, I would think that there is no problem... but I would like to be sure, because if it won't work, I have to sell it before leaving the country.

Something that worries me is that this phone is a latin american edition (notice the L at the end of the code number of the edition). Does it mean that it is meant not to work in other areas?

How do I know if it is unlocked for, say, AT&T? Is there a way to check before actually going there?

Thanks in advance. If any more information is required, don't hesitate to ask.

According to GSM Arena, this model supports HSDPA 850/1900. So it will work on AT&T 3G in the US. On T-Mobile, it will work only on EDGE, sinc they use AWS1700 as their frequency for 3G.
