BlackBerry Curve 8530
The battery cover is stamped with 3G and the network coverage indicator on the phone also reads 3G.
No its not just 1xRTT
There is EVDO and EVDO RevA
but honestly I have had phones on both
and I never noticed a speed difference.
As long as the phone says EV or 3G in the status bar your good to go.
If you have a dedicated usb data card for a laptop
thats where you might see a slight difference, but on a phone I wouldnt worry about it.
The BB 8530 is a great little phone.
Plus Wi-Fi is always going to be faster than 3G anyway.
