Okay , i just saw this app called andRO which you can emulate official servers and play it in your android phone. I read that they still have no plans to support private servers but they would allow server owners to set up andRO server for themselves.
Read it here : roworkshop.com/andro/main/index.html
What i'm saying is... if it's possible, why don't the owner of fRO set up a server in andro. It would be super cool if I can play fRO in my phone. /lv :D
