Excerpt: the phone is good but not great i'm a former blackberry user switched to android and quite frankly the phone is not up to par to fully enjoy android, and when i mean enjoy i mean playing games on the phone its good for low graphic games in 2D sprites but full 3D games lag, i've come to understand and like both the android and the galaxy ace once you pass that sour taste you'll be using your phone to the best of its own limits and that where the ace shines.
Pros: Good looking phone, Good camera, Good for social apps e.g. twitter, facebook, Great for 2D gaming, Good battery life
Cons: U.I lags, Low Ram, Low prossesor, Not that good for 3D gaming
Summary: This cost $184 but isn't worth $20 or even free. When it said SIM CARD CRASH for my AT&T SIM that works perfectly over another phone, I tried not to blame the phone and went ahead to get a T-mobile prepaid. I discover that the internet speed is exeedingly slow (2G instead of 3G). I again take it as a service provider issue and don't blame the phone. I buy a T-mobile prepaid (at least the card gets read though the internet speed is lousy at best).
Not International version GT-S5830 i is international version 3G max

Summary: Too many and almost all sellers on Amazon are selling the non international version as international. I had bought the international version in UK last year. It should say GT-S 5830 i and not L or anything else. The international version is really the best one and very high quality compared to what is sold here in USA as international version. Beware people ! Most importantly keep in mind its internal memory is very limited 150 MB.
Summary: I bought this phone after reading good reviews on it. And while the phone itself preforms okay, I say okay because the in phone storage is inadequate and even with a SD card I can't down load many apps to my phone because the internal phone storage wont allow it. Someone said the battery life is good but I think it is poor, mine doesn't stay charged for more than a couple hours if me or my kids are playing games on it.
