I'm working on a Tmobile G2 with Android 2.2 and my thoughts of aeriamobile are....
Its outstanding and gives me quick access to forums/shoutbox when I have nothing to do during class if I don't get caught lol.
It works perfectly fine for me not having any problems with the features it offers so far. Over time I'm sure it will expand and grow to a fan favorite base of using Aeria to where we can purchase AP using our phones and buy item mall materials and hopefully some browser games.
Lastly, It would be a lot better if this was a Application instead of a website since for most Android phones I realized using the web runs your battery a lot faster then when your not using it. So if its possible in due time to make it a App that would be great.
