iphone合同到期了， 想解锁后在国内用
at&t发了解锁指示
Ensure that you've waited the recommended wait period provided by your
carrier.
Back up your iPhone.
Erase the contents of your iPhone.
Swap the old SIM card with the one for the new carrier.
Complete the setup assistant and restore your backup.
现在做第四步， 插入新的， 就是联通的sim卡后， 显示：
"The SIM card inserted in this iPhone does not appear to be supported. Only
compatible SIM cards from a supported carrier may be used to activate iPhone
. Please insert the SIM card that came with your iPhone or visit a supported
carrier store."
这个是说不支持联通的卡吗？ 求助啊。。。
