hey this seems like a very worthy phone. i have a few questions. so does rooting apply to all android phones? and how much mb does an app usually take up? whats the latest android os?
It is indeed a very good phone for it's price
I don't know if it's for all android phones, but as far as I know, almost all android-based phones can be rooted

( someone correct me if i got this wrong )
Depending on what kind of app you use.
Browsers can be around 2 ~ 5 mb ? The browser I use is around 2.5+ mb , just to give you some ideas
Games can really vary from <1 mb ~ 30 mb ?
As for the rest...They don't usually take up alot of space.
But if you install alot then it's a different story.
Oh and, SGA has relatively low internal memory, only around 130mb+ to spare when it's fresh ( someone verify this for me ? i forgot ). The rest is taken up by the OS and pre-installed apps.
The latest OS for this phone would be the leaked Gingerbread version 2.3.3 ( S5830XXKPE )
Official one would be S5830XXKC1. ( can be obtained from Samsung Kies ) This one is Froyo version 2.2.1.
Hope this helps !
