I'm going to India next month and I'm worried about getting a huge bill when I get back. I'd like to leave APN (which I think is phone data) and the actual phone disabled, but still do WiFi. I'd like it to be fairly fool-proof, in other words, I don't want a phone power-cycle to re-enable everything. My phone is rooted and I have utils like Quick Settings and JuiceDefender which I believe can do most of this. Any thoughts?
PS - I must confess that for all I know my Droid won't even get service in Germany (layover) or India, but I'd like to be sure.
