I have iPhone 4s, after i updated my software to 7.0.4 my wifi stopped working. The wifi icon at the top is gone. Its annoying that i have to us my data all the time. I've tried the network reset, it didn't work. My phone works fine, just a lilttle bit slow before i upadated to 7.0.4. And now not only the wifi, the phone itself is slower than ever. I wish i didn't udgrade to iOs 7. There's too much problems. There's this one time that I can't send iMessage at all.

Hi s.kouris,
I'm afraid that unless you are able to contact the previous owner and have him wipe the device, or provide you with his Apple ID password so you can delete the iCloud account, you are out of luck.
With iOS 7, an Activiation Lock was added to deter thieves. This lock prevents anyone but the owner of the device from deleting the iCloud account and restoring the device:

Unless you are able to reach the original owner and get the device wiped or the iCloud account deleted, you are stuck with a brick.
Sorry,
GB
