The iPhone will play a "prominent role" at today's T-Mobile "Uncarrier" event being held in New York City, according to CNET. T-Mobile is expected to use the iPhone to showcase its new no-contract service plans which were rolled out over the weekend.

The carrier hopes its new no-subsidy model will attract customers since they can pay for smartphones and data in smaller monthly installments. This will allow customers to avoid restrictive two-year contracts and costly data plans by paying for new devices such as the iPhone 5 themselves. T-Mobile is also expected to roll out its new 4G LTE network on Tuesday.

Spruce up your reminders with a handy countdown app. Reminder & Countdown free covers all the bases when it comes to displaying how much time is left until an event or holiday. Anything at all can be logged with a time and Reminder & Countdown will automatically alert you before or when it happens.

Reminder & Countdown free version 1.5 requires iOS 5.0 or later and is optimized for the iPhone 5 display. The app is supported by small banner ads at the bottom of the screen, which don’t interfere with the reminders or functionality of the app. Upon first opening Reminder & Countdown the master list of events appears along with real-time countdowns.

Earlier this year T-Mobile announced a plan to offer its customers more flexibility by eliminating cell phone subsidies, and the carrier has followed through by rolling out its no contract data plans over the weekend. Instead of subsidizing cell phones and locking customers into two-year contracts, T-Mobile users can now choose one of several monthly data options. The plans start at $50/month, all the way up to $110 for 12.5GB/month. There is also a $70 unlimited option, and each plan comes with unlimited talk, text, and tethering.

The catch is customers will be forced to pay full prices for new phones, but at least there will be an option to do it in installments. For example, you can secure a $400 phone with a small down payment, and make monthly payments until it's paid off. T-Mobile hopes this will be a better and cheaper option for customers than what AT&T, Verizon and Sprint are currently offering.

Remind Me Later can be a useful feature of iOS, except that it’s limited to reminding you about phone calls only. Fans of the feature will be happy to know that the jailbreak tweak AnyReminder makes it possible to add these reminders to other iOS apps, such as Messages and Mail.

For example, say a text message arrives and you device is locked. With AnyReminder installed, tapping the camera grabber displays options to Dismiss, Launch or Remind Me Later for this particular alert. This menu can be enabled to work with Notifications, Safari, Mail and Messages in addition to the Phone app.

Notification banners that pop up on iOS can be informative but they don’t hang around very long. There’s no way to change the length of time these banners display on the screen, they mysteriously go away by themselves. Sometimes you’d like the message to stick around a little longer.

Now on jailbroken devices the a handy tweak will keep notification banners as long as you prefer. Sticky Icky will wait until you dismiss the banner to remove it from the screen. Don’t mind the name, this tweak gets the job done if automatic banner dismissal is not for you.
