For the iPhone fans: http://www.tmonews.com/2011/12/unlocked-iphone-spotted-running-on-t-mobiles-3g-network-its-true-sort-of/
No, I’m not crazy and yes, this story is about an iPhone running on T-Mobile’s 3G network. Yes we’re talking 3G here because only the iPhone 4S really supports what T-Mobile quantifies as 4G anyway. A small, unknown factoid about how T-Mobile is handling some of its spectrum refarming is that in certain parts of the country, they are using the 1900MHz band (known as the PCS band) for HSPA+. We’ve come to expect that any time we’re talking about T-Mobile’s 3G and 4G phones, we’re talking about phones that operate on T-Mobile’s AWS band of 1700/2100. Well, depending on the part of the country we’re discussing, T-Mobile is utilizing spectrum on the 1900MHz band and because of this… Some unlocked iPhone users are picking up 3G signals.
For instance, this user from Howard Forums was one of the first individuals to bring this to our attention and then we went to work. Of course by going to work we mean talking to TmoNews resident spectrum guru Conan Kudo who broke the whole thing down:
First and foremost, the area we’re specifically talking about is Nevada as that is where this individual unlocked iPhone owner lives. However, Nevada, parts of Northern California and the Pacific Northwest are also seeing some pockets of 1900MHz spectrum refarming for HSPA+. There are other parts of the country T-Mobile can refarm the 1900MHz spectrum but, the focus is on the Pacific Northwest, Nevada, Utah and California for right now from what we’re told. We should emphasize and emphasize greatly that this post does not mean that all of the aforementioned areas are seeing this refarmed spectrum, just pockets inside those areas.
