Setting Up Straight Talk iPhone MMS on AT&T locked phone
As you may or may not know, your MMS will not work with your iPhone when using the Straight Talk SIM card program unless you jailbreak your phone. This means you cannot send multimedia files via text message, this includes pictures, sound files and videos. Here, we will show you how to set up your iPhone so that you can send such files. Before we get into the process, there are a few terms to understand.
What is Jailbreaking anyway?
Jailbreaking is removing the limitations placed on the phone's operating system. The reason we want to jailbreak our Straight Talk to be iPhone is to unlock the Network setting screen so that we can enter Straight Talk's MMS proxy which is different than AT&Ts. For obvious reasons, an AT&T locked phone does not allow access to these settings which is why your MMS does not work with Straight Talk. If you've yet to purchase your iPhone for use with Straight Talk, opt for an unlocked iPhone so that you don't have to worry about this. Be aware that Jailbreaking your Straight Talk iPhone will not unlock it. So you can't use the jailbreaking process to activate your iPhone with TMobile. Unlocking is a completely different process.
Will Jailbreaking for MMS void my iPhone's Warranty?
Maybe. Jailbreaking is a completely reversible process. You can restore your phone back to new at any time assuming your phone is still operational. If you experience a malfunction that prevents you from restoring, then you may be in danger of loosing your warranty assuming Apple can somehow get into the phone and discover the jailbreak. I do not know to what extent Apple researches this in such cases so proceed at your own risk.
Do I have to buy Software to jailbreak my iPHone?
No! All of the popular jailbreaking tools are free. Don't get scammed by online marketers into thinking you have to buy their software and/or instructions to perform a successful Jailbreak! Sadly, lots of Google searches return such scam sites as the top result. Don't fall for it! Let me repeat, DO NOT PAY FOR JAILBREAKING SOFTWARE OR INSTRUCTIONS!
