I have an ATT branded HP Pre 3 that I have had for a few months now on ATT. Since I am a broke college student, I saw a few others who have succesfully switched over the straight talk network using their SIM Card. I have the correct APN settings from straight talk and verified them through some of the other posts seen around here.
My problem is that whenever I enter in these APN settings in the dialer APP for some reason they do not save. Whenever I hit save or setup anyway (since I get an unable to setup APN error) I come back to the APN settings and it is back to Automatic again and requires that I re-enter all of this info for both Internet and MMS. I've seen solutions in the forums but it seems they only applied to changing a file that no longer exists in 2.0+ devices. I've also been at this for days randomly entering the settings in over and over again, still doesn't work so i'll give up on that approach.
Anyone know a way I can get these settings to stay and hopefully get this to work. Saving money is a pain sometimes.
