T-Mobile USA has just begun selling Micro SIM cards specifically targeted to iPhone users, fueling suspicions that the iPhone 5 may come to T-Mobile when it is released. The Micro SIM cards will work in unlocked GSM iPhone 4s, but the iPhone 4 cannot currently access 3G on T-Mobile’s US network.
If you already have an unlocked iPhone 4 and are looking to switch to T-Mobile for your service, this will make the transition a bit easier – just ordering the SIM card and choosing a plan are all that is involved, then just slip the new SIM into your iPhone, and you’re ready to go.
