SAN FRANCISCO: Apple and Google appear to be tightening their grip on the global smartphone market, according to the latest figures.

After unprecedented online interest caused Apple's systems to crash, the iPhone 4 went on sale in high-street stores in the US, UK, Germany, France and Japan last week.

The company saaid it took more than 600,000 orders on June 15 alone, the most it has ever taken in a single day, and now believes sales of its latest handset will soon reach the one million mark.

Elsewhere, Google reported that daily sales of devices running its Android operating system had risen from 100,000 to 160,000 in the past month.

In contrast, Research in Motion, which makes the BlackBerry, has released disappointing sales figures for the last quarter, prompting a decline of almost 5% in its share price.

As Apple fans queued to buy the new iPhone model, Toronto-based RIM stated it had shipped 11.2 million devices in its first quarter, ending May 29, and added a net 4.9 million new subscribers.

Although the company sold its 100 millionth BlackBerry during this period, its results were at the bottom end of its forecast in terms of purchases and new customer acquisition.

RIM's disappointment followed a worse setback for Nokia, the leading smartphone maker, which has warned that its second-quarter profit will miss previous projections.

Gartner, the research firm, estimated last month that Apple's share of the worldwide smartphone market now stands at 15.4%, up from 10.5%, with devices using Google's Android operating system up from 1.6% to 9.6%.

In the US, smartphones are expected to represent 50% of all handset sales next year, up from less than 20% in 2009, according to Nielsen.
