I have a iphone 4 here with 4.1.2. I jailbroke it with limera1n and i activated it by using my airvoice sim card (for those of you that dont know, airvoice is a sub company of at&t and will work in any iphone) and as of right now airvoice does not have web. so i tried turning off data network, but still every time i go to sms a message will pop up saying saying could not activate cellular data network. is there an app or anything i can do to completing disable that message or data? thanks in advance!!!
