IPhone – how to upgrade unlocked iphone 4s to iOS 7.0.4

From my understanding you can only use an unlocked sprint iphone 5 on tmobile with edge network connection. Here is the info that I have found.

Sprint/Cricket/Virgin Mobile iPhone 5 can only be unlocked for T-Mobile / Simple Mobile and may only get Edge. It may also have issues with data/mms so you may or may not get internet or MMS (picture messaging). This is happening to some Sprint iPhone 5 devices and we are working on a fix. THERE ARE NO REFUNDS IF YOU HAVE A SPRINT iPhone 5 and experience issues with data/mms.

sAM tickets were only available for a week on April 2012. Apple was able to patch the servers at that time but a lot of iPhone 4 users waiting for the 4.11.015 baseband unlock was able to get it. sAM doesn't work on iPhone higher than 4 since this is the only iPhone available in April 2012 . Don't assume it will work for the iPhone 5 since you need a ticket that is no longer available
