San Francisco: Apple Inc looks set next week to unveil its much-awaited new iPhone, which analysts say will have a bigger screen and work better with remote computing services.

The invitation did not have any other details, and an Apple spokesman would not provide further information.

The new iPhone would be the first major product introduction under chief executive officer Tim Cook, who took over full-time after co-founder Steve Jobs resigned last month.

It was unclear if Jobs, who is now chairman, will take the stage at the event.

“This is the iPhone 5," ThinkEquity analyst Mark McKechnie said of the event.

Though a good product, the current iPhone4 could use some improvements, he added. “We talked about it having a bigger screen, a dual core processor, and probably integrates pretty well with the iCloud."

The iPhone -- introduced in 2007 with the touchscreen template now adopted by its rivals -- remains the gold standard in the booming smartphone market.

Apple introduced the iPhone 4 in June 2010 in black 16 gigabyte and 32 gigabyte versions, with white ones added to the lineup in April. The company typically refreshes its iPhone lineup during its developer event in June, but delayed the new model this year.

Apple sold 20.34 million iPhones in the third quarter ended 25 June, which analysts say helped it vault past Nokia and Samsung Electronics to become the world’s biggest smartphone maker.

Shares of Apple were up 0.5% at $405.26 in midday trading.
