How can I prevent the signal and 3G icon from turning it to white icon when my connection to Google server is lost? I have a limited plan for mobile data usage(only 100MB per mounth) so I use mobile data for sending/recieving MMSes and for browsing only. I have mobile data turned off 99% of time. White signal bars are hard to see, so I would like to know, if there is any way to turn the "icons goes white while not connected to Google servers" funtcion off?
You have to edit your Framework-Res.apk. Its a bit complicated and differenct on every phone. So I can't simply provide a guide. 

But I suggest you, to ask in your phone forum on xda-developers.
