Since news of Wofford's lawsuit hit the Internet, Hill said his firm has been contacted by many other iPhone owners around the country.
"My e-mail is jammed – with people in California and, in fact, now across the nation," he said. "There is considerable interest to say the least."
He said the firm plans to hold a discussion in the next few days on whether to amend the suit to accommodate new class members.
Wofford seeks $5,000 for herself and each member of the class, as well as other damages.
Despite the patch Apple released to fix the iOS4 issues, iPhone 3G and 3G customers continue to complain about degraded performance on Apple's discussion threads.
"Since I updated my Iphone to the 4.0 is working really slow. Now I have the 4.1 but still the samew [sic], even I erased all the data because I thought that was too full, but even that didn´t work," one customer posted early today. "The 4.1 is much 'pretty' than the older one, but really deteriorates the 3G performance."
"As many people here, my iPhone 3G was very slow after update to iOS 4.0. I had hoped that the problem would be corrected with iOS 4.1. But it is still the same. After a few months, i'm fed up with waiting !," another owner wrote on Oct. 31.
Since June 24, one discussion thread in Apple's forums has accumulated more than 1,600 comments.
