San Francisco , California ( CNN ) -- Just after Apple CEO Steve Jobs debuted the next version of his company 's iPhone to the world , the tech luminary had a bit of technical trouble . `` Well jeez , '' Jobs said , struggling to get the spanking new iPhone 4 to do much of anything without a connection to a Wi-Fi network . The technical faux pas came during Jobs ' keynote address at Apple 's Worldwide Developers Conference in San Francisco , California . At one point , Jobs turned toward the audience and seemed to ask a question of one of his technical directors : `` Got any suggestions ? '' he asked . `` Verizon ! '' shouted an audience member , in reference to the fact that AT & T , the sole cellular network that carriers the Apple iPhone , gets notoriously bad reception in San Francisco . Many tech bloggers and writers have called for Apple to open the iPhone to other networks , including Verizon Wireless . That did n't happen on Monday . The new iPhone will remain an AT & T-only device . It goes on sale on June 24 to AT & T customers for $ 199 or $ 299 , depending on the amount of storage . Any AT & T customer eligible for a phone upgrade this year can get the iPhone 4 on its debut date at those subsidized prices , Jobs said . After the event , tech industry analysts warned against reading too much into the network glitches during Jobs ' presentation . But , if nothing else , they do symbolize the growing frustration some phone consumers have over the lack of choice among wireless carriers . In a recent interview , for instance , Kevin Tofel , a blogger in the GigaOm network , said it is smartest for consumers to pick a wireless carrier first , rather than get the coolest phone . Otherwise , they 're buying an `` expensive brick , '' he said . Analysts said Jobs was having trouble connecting to a Wi-Fi network during his presentation , not AT & T 's troubled 3G network . `` It 's Wi-Fi , '' said Carolina Milanesi , research director for mobile devices at Gartner . `` You had so many people in there using Wi-Fi . I did n't read too much into it . '' Of AT & T , she laughed and said , `` It 's not always their fault . '' Van Baker , research vice-president for Gartner , said the `` Verizon ! '' comment from the audience was `` totally unfair ... because it 's not going over the 3G network . '' Jobs eventually resolved the issue himself . In a joking yet stern tone , he asked reporters and conference attendees to stop using Wi-Fi networks so that he could finish the presentation . Some 570 Wi-Fi stations were clogging up the connection he needed to complete the presentation , he said . If the attendees did n't comply , he said , he would simply not be able to show off the rest of the iPhone 4 's new features , including its higher-resolution screen , improved camera and video chat functionality -- which , by the way , is only available over Wi-Fi .
