I bought an unlocked Samsung Galaxy Sprint and had it flashed to my Cricket network. Everything works except for the 3g. Other forums say to change the APN settings, but there is no APN settings option on the entire phone. Airplane mode is turned off, so I know that's not the problem. How can there be no APN settings option? Any other ideas? Also, when I get it flashed to Cricket (I've done this twice now), the 3g works for about a day and then goes away.
