I know that alot of android programs promise this, ex: apn on/off, apn droid, apn manager..none of these seem to work for me. I have the Lg optimus one with google (p500h) with the most recent firmware update. I have an unlimited text message package, but in order to send or receive a picture or video, I have to turn on my G3 (which I keep off all the time). I have no data plan and have no use for one, so the instant I turn my G3 on, one of my android programs automatically goes on the net in search of an update and I get hit with a "pay per use" charge..at least thats what I think is happening. I've found the APN list on my phone, and apparently i'm able to create new ones if I want. I've looked through the values of the 2 default ones that are already there...I don't understand enough of what is there...I see values for mms and am tempted to create an apn with those values inputed and all other fields blank, but I don't expect that will work. I doubt i'll find a program that helps me as 3 have already failed. I'm thinking of phoning the tech department of my service provider, but i'm sure they'll be against helping me fiddle in this way. the description of the mobile data charges is "pda", which is why I assume that its my programs trying to update automatically thats doing this. I've been looking for a pda blocker, or a program that restricts what parts of the phone can have internet access without asking, but i haven't stumbled accross one. I'm still thinking that a manual switch to a custom apn to accomplish this is probably my best bet, I just don't know how to do it. advice please? thanks.
