Screen yellowing. Wonky cameras. An antenna that hates left-handers. If you take even the most cursory of glances around the Internet, it makes it seem like every iPhone 4 to come off the production line has one issue or another — but are the problems really that widespread?

Now that everyone has had at least 24 hours with the device (with an apologetic exception to all of the Best Buy/Walmart/Radio Shack pre-orderers that left empty handed yesterday), I’m interested to know: are you having issues with your phone?

We’ve got at least a handful of iPhone 4s amongst the TechCrunch Network’s battalion of writers, and most of them seem to have at least one notable issue. My personal unit is a shining example of the left-handed antenna shorting problem; one finger across the left band, and my signal plummets from 5 bars down to 0. My screens never shown the slightest hint of yellow (an issue which is purportedly caused by the still-wet glue not having dried yet after its trip from the factory), and the camera/proximity sensors work like champs. It does, however, have a terribly hard time staying connected to WiFi networks running on certain channels.

Are you having issues with your iPhone 4?
