As iPhone 4 buyers prepared to unbox their new smartphones on Thursday morning, some screamed with joy. Others trumpeted vuvuzelas.
But shortly after testing out the world's new "it" phone, some of those consumers turned to the internet to report problems with the new Apple product.
On Web forums and on blogs, some consumers posted videos and rants about the iPhone 4's new antenna, which is built into a metal rim around the phone and, some claim, causes the phone to get unnecessarily bad reception.
The blog Gizmodo has posted a roundup of the complaints. Several people say that when they hold the iPhone 4 by its metal sides - essentially, when they're touching the antenna - the reception gets worse or drops.
