Carrier charges money for iPhone unlock
Hey guys. So, straight to the point. I have an iPhone 4, purchased from Omnitel by a person (not a company). Contract has ended around 2 years and 4 months ago. However, Omnitel states that I must pay 100LTL (around 40$) for a factory unlock. They say that I have 1 month time after the contract has ended to unlock my phone free of charge. After that they refuse to let you unlock the phone for free. However, in the list (http://support.apple.com/kb/ht1937) here, Omnitel doesn't seem to even offer Carrier Unlock. This information is probably out of date, but is it possible to actually get my phone unlocked free of charge? Like if I send my IMEI directly to apple, with a print of my contract? I do not want to pay for something that all (if not, then most) carriers offer for free with no expiration date. Thank you in advance!
iPhone 4, iOS 7.1
