Would it show as unlocked now even though I'm still using AT&T service? Just wanna make sure because it was a complicated transaction when I bought them through Apple (wasn't supposed to buy them at full retail but had to, due to a few issues).
Also, I've read that when bringing and unlocked AT&T phone to T-Mobile, it will run only on HSPA21, which is slower data and not 42. Is this true ? Or just an old article
