Passionate techies may be clamoring for 4G connectivity in the iPhone 5, but a facepalm-worthy percentage of existing iPhone owners think their beloved iOS phone already has it, a new study from Retrevo suggests.

Of a sample audience of more than 1,000 smartphone users surveyed last month, 34% believed their iPhone supported 4G connectivity, despite the fact that most recent model only sports a 3G antenna.But they weren't alone; similarly, 24% of BlackBerry owners believed their devices were 4G-enabled although RIM has yet to release a 4G handset.Interestingly, the same study found that 61% of the iPhone owners polled didn't care whether 4G services would be available in the next version of the iPhone.Do you own a 4G-enabled device? Do you care to? Will you be buying one soon? Sound off in the comments section below.
