Hello guys, First of all im pretty new here and my english isn't that good so excuse me for that. I worked at a company in England and I got a iphone 4s from them to use for business. After 1 year of working there they went bankrupt. I was able to keep the iphone but after 2 days it didn't work anymore. I called o2 and they said that is was blacklisted or something. I went back to holland because I live there and i tried a other sim card from 'Tele 2' in the iphone but in the netherlands it said 'Activation required'. I went to the local phone shop and they said they could unlock it for around 120 euro to 190 euro. Isn't there a free or cheaper service to unlock/unblacklist it. Btw the iphone 4s is running iOS 7. Thank you.
