When Apple launch theiPhoneon Friday , it is set to get a parachuting on its contender and spark a flurry of raw earphone designs , regardless of how well the twist actually sells .

By introducing a combined smartphone , mobile e - mail platform and MP3 music player with a touch - screen interface , Apple has post other hardware vendors running back to their drawing plank . And the company has enjoy positive press coverage since CEO Steve Jobs announced the iPhone in January , analysts read .

Apple is feeding the fire withstrong advertising in its retail stores . On Monday , staffers at theApple Store in the Cambridgeside Galleria mallin Cambridge , Mass. , wear disgraceful T - shirt with the logo “ the wait is almost over , ” print above an trope of a calendar page for Friday , June 29 .

IPhone expectancy has already make a “ nimbus effect ” of increase sales for Apple ’s notebook and screen background microcomputer , an wallop that is likely to increase after the launch , consort to a composition fromChangeWave Research .

Apple posted a strong profit for its fiscal second quarter despite struggling with a U.S. federal investigation into executives backdating their line options . In April , Apple gravel Wall Street expectations by posting a profit of $ 770 million for the March quarter , an 88 pct rising from that period last class .

Since the companionship has already garnered media attention and a sales boost from iPhone demand , Apple will suffer slight wrong even if the twist is a bust in retail sales , one analyst allege .

“ No agency Apple will seriously impact Nokia or Motorola or Samsung , who mix sell over a billion phones a twelvemonth . But if Apple manages to sell several million , then that is in all likelihood fairly good for their overall business , ” said analyst Jack Gold , founder of the research firmJ. Gold Associates . “ I retrieve the potential Au mine is in the services , not the phone hardware . ”

The iPhone will lend new reader to Apple ’s iTunes on-line music store and Apple could make more money if it settle to plunge succeeding wireless mobile intersection like pilotage , location - based services , VOIP ( voice over Internet Protocol ) telephony and telecasting streaming , Gold enunciate .

In the meantime , Apple has already given a headache to competitors scurrying to catch up , such as Motorola , Samsung Electronics , and LG Electronics . Even vendors with like products — like Nokia’sN Seriesand High Tech Computer’sHTC cutaneous senses phones — lack Apple ’s seal and will have problem competing on store shelves , he say .

In fact , some experts are warning that iPhone sales could pass short of Apple ’s high-pitched expectations . Their criticism includes potential exploiter muddiness about Apple ’s “ virtual keyboard , ” a electric battery that may blow over too tight and is not substance abuser - replaceable , and resistance by some corporal IT department to the added expense and security department risk of corroborate mobile e - mail electronic internet in add-on to the server they use to support Research in Motion ’s BlackBerry gadget .

Those drawback could limit the iPhone ’s success in the business market , say Shaw Wu , an analyst with American Technology Research .

Still , the iPhone will be popular with those who tend to expend smartphones more by scroll through menus than typing long message , and who have made Apple ’s iPod music player a immense bang despite similar concerns about its barrage , Wu said . Likewise , consumer will likely shrug off corporate security measures concern , and use mobile e - mail system from Google and Yahoo .

In the long run , Apple will use the iPhone to beat its competitors in creating an end - to - end channel for digital medium , traverse from Mac personal computer to the peregrine iPod medicine player , iTunes on-line memory and Apple TV circle - top boxful for sharing Internet and goggle box video message . The only thing Apple could do to spread that profit even wider would be to offer iPhone models at less than the current $ 499 for a 4 GB version and $ 599 for 8 GB , Wu say .
