Though he declined to specify how much his clients would seek in financial damages, he said that given the expense of the phone, plus the monthly data and voice plans from AT&T, they are "not insubstantial."
"We feel very strongly that Apple has done something wrong and AT&T was complicit," Ward said. "And collectively consumers can and are speaking and I hope Apple hears us and is willing to resolve it."
Despite the outcry from consumers and this latest legal complaint, tech analysts familiar with previous iPhone launches say Apple will find a way to work through this as they have in the past.
"With every launch of a new iPhone, we have teething problems," said Rob Enderle, principal analyst at the Enderle Group.
In 2005, Apple compensated some owners of first- and second-generation iPods with $50 of in-store credit or $25 cash to settle one of its earliest class-action suits over the batteries in an older edition of the iPod. It also faced lawsuits over its first-generation iPhone in 2007 and its 3G iPhone in 2008.
Apple typically leads with design and then follows with engineering, Enderle said, which can lead to glitches.
"This is one of the risks Apple takes with its approach and they're definitely willing to take that risk," he said.
Ultimately, Apple will find a way to address the problem, he said.
"I think Apple will work through this - they typically do - [though] this is a little tougher product launch than we've seen in the past," he said. "But a year from now, we'll probably forget it."
