Question on unlocked SE xperia Arc data speeds

I received an unlocked SE xperia arc and would love to give it a try but when I put in my sim card from my previous smart phone, I get voice and text to work but very slow (2g) internet speeds. I have changed the sim card, registered the phone with ATT but still no sucess. 

 

Do anyone know if it is just standard practace for unlocked phones to only get 2g speeds with ATT or is there a setting that I am missing? 

 

Thanks

Re: Question on unlocked SE xperia Arc data speeds

There are two versions of the Arc (LT15x), International and American.  Using the 'i' version you will only get 2G on AT&T.

 

3G NetworkHSDPA 900 / 2100 - LT15i
 HSDPA 850 / 1900 / 2100 / 800 - LT15a

It varies, but I can get up to 1125kb/Upload, 1755kb/download. Sometimes faster, sometimes slower. All on H (HSPA) 3.5G.

Make sure it is a LT15a, the a is for the North American market. I had the X10a, lost it, got the Arc are a great price on Amazon. Very satisfied, and I like that I'm unlocked!

And ignore the LT15i; my phone is the LT15a.
