First,congratz for ur new toy. It's so fast,right? V6 maxx is a good phone.
1. You can use Rsd lite 4.1 to flash V6.To find the right mp,You can search in M3. But,make sure you check your BL version and your firmware version. Is it LD or VL version?
2. To change skin, you can use SkinManager.
3. I haven't tested by using network connection. I used to use MPT.
4. V6 Maxx is a P2k05 platform so You'll feel a different taste n a brand new experience in modding. Don't forget that you can play RealFootball 3D now with no lag at all..
I'm using Darkness Mp now but I gave my Maxx to my sister.
Maxx also has a good sound thru speaker n headset if You have modded the audio.cfg.
Have fun wit your Maxx. I'm posting by using OM.
Don't forget the cool funlights V6 has.It'll make your friends jealous coz it's so damn cool..
