We’re still waiting on Apple to send out the invites for its all-but-confirmed iPhone event on September 10th. While Apple is expected to announce the new iPhone(s) that day, nothing substantial has been rumored about in-store availability, until now.

According to an internal T-Mobile employee schedule, it looks like this year’s iPhone launch weekend will be September 20th-22nd. T-Mobile has blacked out these dates so employees can’t take vacations, which is the typical all-hands-on-deck approach that carriers reserve for new iPhone launches. Another report has said that the new iPhones will go on sale in Japan on the 20th as well.

“Like all good rumors, we should take this with the standard “subject to change” warning but my sources suggest this could be iPhone related,” reports TmoNews. Apple is expected to debut the iPhone 5S and iPhone 5C next month, but it’s unknown if both devices will go on sale during the same weekend.

T-Mobile is abruptly ending its ‘$0 Down Summer Sale’ on the iPhone 5 and 4S tomorrow. The promotion allowed customers to walk out of a store with a new iPhone and no upfront charges. The cost of the phone was then recouped through smaller, monthly payments.

As of Saturday, newer iPhones can only be bought on T-Mobile with a larger upfront payment that more closely matches the subsidized retail cost at other carriers.

T-Mobile only recently started selling the iPhone, and it has proven to be a very good thing for the struggling carrier. By marketing itself as the hip “Un-Carrier” that charges less up front, T-Mobile is starting to see better days.

After the company reported healthy growth in its quarterly earnings report today, CEO John Legere made some comments about T-Mobile’s relationship with Apple. He said the carrier looks forward to carrying a “whole array” of Apple products in the future, hinting at more than just the iPhone. Could the iPad be next for T-Mobile after Apple announces new devices this fall?

For the last four years, T-Mobile has been just battered by the iPhone. Unable to ink the same deals with Apple as AT&T, Sprint, and Verizon to get the Jesus Phone on their networks at a subsidized price, T-Mobile tried to sell itself to AT&T, only to have the deal killed by the FCC.

In desperation, T-Mobile tried a new approach: they decided to call themselves an “Un-carrier” and start offering untraditional no-contract, upgrade-anytime-you-want plans. And you know what? It’s really paying off for them.

T-Mobile’s new summer smartphone promotion is a scorcher: The carrier has eliminated down payments entirely and dropped the price of all devices to $0. Even the latest handsets like the iPhone 5, the Samsung Galaxy S4 and the Sony Xperia Z are included in the hot new deal, which the company announced today.

But there is a catch.

AT&T’s new early upgrade program is “calculating, sneaky, underhanded,” according to a new print ad from T-Mobile that will be published in USA Today.

AT&T Next is designed to let customers upgrade their smartphone more often — once every 12 months — and it is a direct competitor to T-Mobile’s new Jump plan. But T-Mobile has been quick to make its feelings about Next clear, accusing AT&T of trying to take more money from its customers.

As a response to T-Mobile’s new Jump plan that allows customers to upgrade their smartphone once a year for free, AT&T announced Next two days ago, which offers similar perks as Jump but at a much higher cost.

T-Mobile’s CEO, John Legere has already launched an AT&T Next bashing campaign to go along with the anti-AT&T rant filled keynote he delivered on July 10th. According to an email exchange with CNET, Legere views AT&T Next as just “a poor copycat” of Jump that’s designed to ripoff consumers more than ever:

T-Mobile is hosting a big keynote today to announce a couple of new products and features that are coming to the network. So far the most exciting news is that customers can  join the new “Jump” program to upgrade their smartphone twice a year.

Ina Fried at All Things D got the scoop on the other new announcements so you don’t have to watch the event yourself. Here are the Cliff Notes of what T-Mobile will announce:

Android has held a pretty sizable lead over the iPhone for a long time now, and in the United States, it would appear there’s little chance of that changing any time soon. But Apple’s smartphone is gaining ground on its rival, and it’s all thanks to T-Mobile.

T-Mobile finally has the iPhone 5. It’s great, and cheap, but unfortunately its data speeds are slower than an iPhone 5 on AT&T. Not satisfied with their slower iPhone 5s, Joseph Brown and Sky Zangas did some digging around in carrier update files and figured out a way to boost data speeds on the T-Mobile iPhone 5.

To get faster data speeds on T-Mobile’s network with the iPhone 5 all you have to do is install a custom carrier update. That sounds like a tough task, but it’s actually pretty easy, and thanks to the guys at TmoNews, here’s a quick guide on how to do it:
