Rumor: Texas Instruments making chips for Apple's next iPhone ahead of Sept. launch

An "inside source" claims that Texas Instruments is already producing power management chips for an as-yet-unannounced Apple handset, which the company's management is reportedly calling the "iPhone 5," according to a post on iPhone repair firm RepairLabs' blog.

Texas Instruments currently supplies a number of components to Apple including the touchscreen controller in the iPhone 4S as well as power management chips and a control device found in the new iPad.

Going further, a separate Chinese source said that the "iPhone 5" will be ready for a September release. The unnamed source also claims that the handset will feature a larger display, though didn't mention specific dimensions.

While RepairLabs does not have a proven track record of providing rumors later proven to be true, the company did post pictures of the new iPad's back casing in February, which allegedly came from the same chinese source mentioned above, and was one of the first to investigate the third-generation tablet's purported heat issues.

The latest rumors come on the heels of a report earlier on Wednesday, claiming that whispers from China say Apple is working on a 5-inch Retina Display device set for launch in 2013.
