U.S. mobile carrier T-Mobile may still be a number of days away from its annual Un-carrier event, but that hasn’t stopped the company’s enigmatic CEO John Legere from letting the cat out of the bag in relation to one product that will be discussed during T-Mobile’s Un-carrier X announcement – the 4G LTE CellSpot.

According to a new survey by Retrevo, people actually “believe” that the “4” in their iPhone 4 stands for 4G, which is the next generation wireless standard in wireless telecommunication, capable of blistering fast data downloads and uploads.

Leaked AT&T documents from the last of LulzSec’s hacking endeavors reveals information about a potential “4G” LTE-ready iPad 3 and iPhone 5.

With WWDC behind us, enthusiasts are starting to look at what’s in store for the next-generation iPhone, which is rumored to be announced within the next few months. A spokesman at Etisalat, a United Arab Emirates-based carrier that currently carries the iPhone 4, mentioned a 4G-based “iPhone 5”.

China Mobile, the state-owned Chinese phone carrier, has announced it has reached a deal to bring LTE-4G to the iPhone. While that in no way means the next iPhone, allegedly scheduled for September, will include the technology, it shows Apple is interested in developing it. The carrier has refused to elaborate or disclose when we would see an LTE-powered iPhone. That’s not surprising, since Apple doesn’t comment on future products and stops its partners from doing so.
