Android :: Symbian To Android Wifi Or Network Access Application

Having seen similar threads i know im not the only ex symbian user, not that i didnt enjoy my time with it but its time to move on! ive tried to see if this question has been repeated elsewhere but i couldnt so i do apologise if i missed it!

on my previous symbian devices n95 and 5800 if i used an app that required web access be that wifi or over the network it always asked me if i wanted to allow this, and i thought it was a good feature. now i just got a HTC desire and for financial reasons couldnt get an unlimited data plan from o2 in the uk just yet otherwise id be happy to let it be on all the time.

now it seems that if you want devices to connect you either have the wifi on or off, same for the mobile network. does anyone know if there is a setting or app or anything in the pipeline that might emulate this symbian function? maybe its me just being a bit funny but i found that level of control good and it didnt mean i had to go backwards and forwards turning stuff on and off. if its not possible im sure ill get used to it but it would be a good feature!

secondly i have a Ford Focus euro model with a built in bluetooth hands free to the stereo, a factory fitted option which i believe uses a nokia Bluetooth module (stereo is sony) now this really is a minor quibble but on the old phones when the bluetooth was on any incoming calls would push the ringtone through the speakers untiill i answered it

using the desire the phone still rings normally with whatever ringtone i have but it pushes a plain ring ring through the speakers, anyone know a way to change that? or mute the phone when it rings and just push the ring through the stereo?
