Apple to Unveil New iPhone

It's clear Apple has big plans Tuesday for its popular iPhone. The question is what exactly can tech consumers expect from today's event at Apple's Cupertino headquarters?

Be sure to visit this post for updates from Apple's iPhone event as they become available. The show starts at 1 p.m. ET.

Meanwhile, let's round up some of the notable rumors and reports:

iPhone 5 or iPhone 4S? Most of the speculation suggests Apple will unveil the iPhone 5, but several recent reports claim the next update might not be as drastic as many think.

Mashable neatly wraps up some of the reports that Apple will unveil the iPhone 4S, which sounds similar to the company's shift from the 3G to 3Gs models. However, the reports appear light on details about what a 4S model would feature.

Last month, the New York Times reported the device would receive notable upgrades, including a faster processor and 8-megapixel camera. Also, Bloomberg -- citing Piper Jaffrey analyst Gene Munster -- reports the iPhone will add overhauled voice controls, allowing users to set appointments, surf the Web and send text or email messages by voice.

Sprint. Several outlets suggest AT&T and Verizon won't be the only homes for the next iPhone. A recent Wall Street Journal report (subscription required) says the wireless carrier will make a "multibillion-dollar gamble" to snag rights to sell the new iPhone. Citing "people familiar with the matter," the report claims Sprint wouldn't start profiting from their Apple arrangement until 2014.

iOS 5. Apple's website says the update arrives this fall, so it's highly possible we'll hear more about the latest upgrades to the iPhone operating system (also for iPad and iPod Touch). Among the key features this update will add: a notification center for alerts, iMessage for iPad and iPod Touch, a to-do-list style Reminders app, Twitter integration, camera tweaks, photo enhancements and the ability to set up and update devices without tethering it to a PC or Mac.

Readers, what do you want from the next iPhone?
