Iv looked around a lot, and have only found older information from years ago about this topic. I have a LG620G with a sim card and a 30 dollar plan on it. And I have a unlocked jailbroken Iphone 4. I ordered a sim cutter already, because I know there has to be a way. I know I could just fork out a little more money and order a micro sim from straight talk, but I'm on a budget right now and don't need the $45 plan or the unlimited data when I'm on a wifi spot all day. Any help would be awesome, thank you guys. Even a redirect to a post on here about this same problem.
