this guide is tested and working on ios 7.04
for this guide to work you will need to jailbreak your device first!
at the moment you can only jailbreak devices on 6.1.2 or 7.04 , so if you were lucky enough to still be on 6.1.2, you can use evasi0n jailbreak directly , otherwise you will have to update your device to 7.04 first
[NOTE] it's recommended that you restore your iphone first to 7.0.4 IF YOU HAVE UPDATED TO 7.0.4 ON AIR(skip this step if you updated using itunes)

Note : if this guide didn't work for you then try the hairdryer method , and then reset your phone.
Heat the places with arrows on them only for about 3-4 minutes (don't over do it) or till you get the message ''the phone is too hot .........". and then turn off your phone and let it cool for 5 minutes in the fridge.
NOTE : make sure to only heat the specified parts and constantly check your phone to see if you got the message described above.
