Straight Talk iPhone 5

I bought an iPhone 5 on Straight Talk from Walmart on March 1 this year. I have been on ST for about 2 years. Before I got this iPhone, I was on an LGC900 Windows phone from ATT, but I switched to ST. I could use internet, apps, etc without being connected to Wi-Fi. Now that I have the iPhone 5 on ST, I can't do ANYTHING but Text and call without being connected to Wi-Fi. Instead of saying "HOME" like on my Windows Phone, it says "TFW 3G". I didn't pay $800 to just text and call. I've gone to http://iapnupdateatt.straighttalk.com to set up my APN, and it did not work. I have dialed *22890 MULTIPLE times to fix the problem, but it did not do anything. I've called ST and they didn't know what was wrong. What can I do to fix this, other than jailbreaking it!

Added (1). I don't want stupid answers. I want answers that will actually RESOLVE this problem.

Whatever

Jail braking it won't help. That will make it work faster. For one, no contract carriers are less reliable the major carriers. Other then that, you Might want to take it to the apple store

The reasons you can't do things together like you used to is becuz they exclusive to att cell service honey.drop ST and get back on ATT where you get more for your money and rollover and free cell to cell with unlimited texting.

You have to call your carrier, a messageboard doesn't work on your service

  • Virgin Mobile iphone or Straight talk iphone? I heard lots of negative reivews on Straight talk iphone and that if youre planning to get a straight talk, you should get a android instead. I seen lots of reviews how their iphone can't connect to the data/really slow and have bad customer service. Although they offer a good unlimited plan, which carriers should i choose to get the iphone? Virgin mobile or Straight talk? I'm planning to buy full price iphone 5 in walmart

  • Unlocking iPhone 3G to Straight Talk? I've been trying to do this for free for a while. I have a SIM card that would work. I just tried unlocking it through UltraSn0w and it says Searching for a while and eventually no service. I've already jailbroken it. There should be service here as I get it on my other phone. How do I get this to work? I'm trying to use the SIM card from my current phone. Not one I just ordered.
