Alright I have had iPods and stuff and I've hail broken those but I just got a iPhone. Now if I jailbreak that is there a way to get free phone service? I don't care if it's illegal or not.
Can I get free phone service if I jailbreak my iPhone?
LOL, Highly doubt it:)
There is an app in the app store called text free with voice for free and in let's you call or text anyone for free but gotta be connected to a wifi router
Nope. You will always have to pay one way or another. There are cheaper methods than using the carriers options straight up, for example, when your getting a data plan, you can just get data, and use apps for texting and calling. Texting is free, but uses data, as with calls, you can use textPlus to call as well, but you need to pay per minute, or similar. Skype is the same method, you can call mobile landlines through skype using skype credits. There may be an app in cydia that I haven't heard of however that may allow free calling, but if there is, I can't help you, you will have to find it on your own. I'd check that out before making a decision.
Also you can unlock your GSM so you can use a different carrier, and get cheaper rates for data plans. However, this is a breach of contract, and you can get in some serious trouble if you get caught. This is only possible after a jailbreak, and bricking your phone is very possible, as this is tampering not just with software, but hardware. Be careful.
I hope I have helped,
No. Jailbreaking only lets you install additional apps on your iPhone. But there is no app that will let your phone work on AT&T or Sprint or Verizon etc. For free, because it's simply not technically possible.
What you *can* do is install a free calling app like Skype, which will let you talk to other people with the same app for free. And you don't need to jailbreak to do that.
No you can only get free apps and games.
