Apple is rumored to release iPhone 5 in mid-October with an upgraded operating system in the form of iOS 5 that contains more than 200 new features.
iPhone 5 would also have access to Apple's iCloud service that allows users to store data such as music files on remote computer servers for download to multiple devices such as iPhones, iPods, iPads, and personal computers running Mac OS X or Microsoft Windows.
California-based Apple is expected to issue press invitations to the iPhone 5 launch on Sept. 14 and it will take place in the San Francisco Bay Area on Sept. 21, according to CultofMac. The smartphone will be released in early October with pre-orders starting Sept. 28.
This forecast falls in line with reports of Best Buy passing on the message to its employees that the iPhone 5 could be released in the first week of October.
Other rumored specifications of iPhone 5 include a near-field communication chip, a 4-inch screen, 8MP camera, world phone that would be compatible with both GSM and CDMA networks, A5 chip with at least 1.2GHz speed.
Meanwhile, speculations are rife that Apple may release the next iteration of iPhone as a 4G phone at least to Verizon and AT&T customers.
As the iPhone 5 release date nears, let's take a look at the 4G smartphones that may give tough competition to iPhone 5.
Google Nexus Prime
If rumor mills are true, Samsung and Google are readying a killer device under the name Nexus Prime, which could give iPhone 5 a run for its money in terms of both OS as well as specifications.
Nexus Prime is expected to run Android Ice Cream Sandwich and feature a Super AMOLED HD display with 720p resolution. Prime's display will include a 4.5-inch panel with a PenTile layout, according to a report from BGR.
Nexus Prime will be powered by a TI OMAP4460 chipset clocking at 1.5GHz. The report added that Nexus Prime won't feature physical Android menu buttons below the screen anymore as everything will be software-based.
In other hardware, the camera will be 5 megapixels, but the sensor is expected to be improved for higher quality images and better low-light conditions. Like many Android handsets on the market, the Nexus Prime will offer a front-facing 1-megapxiel camera for video chat.
The 5-megapixel camera, however, is said to sport an advanced sensor delivering top image quality in addition to superior low-light performance. Moreover, the device would have 4G LTE support and at least 1GB of RAM, the report added.
Google is said to be aiming to launch the device around Thanksgiving.
