Apple ipod

How I can unlock my iphone?!?

I have a jailbroken iphone, and the thing is that I connected to iTunes, said that there was an update available for it. I decided to do the update (basically for MMS messages) but due to the SIM card from another company, the update failed. Was well w / her, I do not care, but once expelled iphone i could not go to the menu or anything. I can only make emergency calls, but I can not put my code card! [The register of iTunes image appears at all times]. I still connect to iTunes and out, but can not run this! what is wrong? can help kids? Thank you very much, Thanks!

you need to download the firmware back to what I had before I found online .. firmware .. determine the version and has been looking for the file .. then press Shift + iTunes restore or something like that when iPhone is connected .. SHIFT exit the Select the file you want the phone be restored .. Just choose which firmware file and click OK. It worked for me in the past. Relocked my phone i doing something similar. You may have to extract firmware for WinRAR Edit: WTF idk FB talking about everything that iPhone can change. not listening
