I have a iphone 3G and its always on the emergency call screen, its using OS 4.2 now and even when i put a sim card in it doesnt work, jailbreaking doesnt work either, please help and yes i put the sim card in properly
Your iPhone 3G must be network locked. A jailbreaking is not required for this. You must unlock your iPhone from network restriction to use it with any GSM SIM card. You can unlock your iPhone 3G safer and easier using remote unlocking service. You can get the remote unlocking service for an iPhone 3G fromSimpleUnlocking.comat affordable cost with easy unlocking guide. This is a permanent unlocking method and doesn't require a jailbreak too. Good luck mate.
