I am unable to delete the ATT APN setting and am unable to add the Straight Talk APN.
I found this website showing the right place in my phone's menu: http://www.att.com/esupport/article.jsp ... 71uNau7RIv
You can see in their step 5 several blank profiles. It let me add a new profile that I named straight Talk. That new profile lets me add a primary DNS address which I put as 066.209.011.033. I did NOT have the option of adding an MMS port, MMSC, port, proxy, or APN.
That same menu would NOT let me delete the ATT profile. I could view the ATT profile, which did include the ATT APN "wap.cingular" but it does not give me the option to delete or edit the ATT settings.
Do you have any instructions I can try to delete the ATT setting and add the straight talk settings?
