iPhone 4 won't work without Sim card after resetting it
Since I installed the new iOS 7.0.4 on my phone, my battery keeps on getting worth. Shutting of at 40% sometimes even 60%. I followed the advice to reset the whole phone. After backing everything up with iCloud today, what literally 12 hours took, I finally started. And then this, since I have that phone ( two years, only for Skype and What's app to stay in contact with family and friends at home in Europe) do I never had any problems because of a missing sim card.
I tried to connect it to iTunes without any progress. I don't need a contract or anything I only use it with wifi at home.
So, are there any solutions out for me?
** and yes I tried an older sim card but still nothing.
