Hello, as you might know, you can cut your T-Mobile sim card into a micro sim. The thing is, I keep getting told it will not work and the data will not be on the sim card and will not work. I want to know this, since I am pretty new to Apple products..I have an IPad 2 4.3.3 jail broken. Is there a app/gadget that enables 3G service without a sim card (I have a 3G iPad). I have unlimited 3G on my contract. I want to use this on my IPad somehow, without a sim card. Tl;dr, I want the 3G I already own, just on my iPad. It is very annoying to carry my phone and connect to it by using it as a router. Please tell me if there is anything on the 3rd party app list that does this. If you have any questions about what I am asking, please ask me.
