Business users meet gatecrashers at UK iPhone launch

Ben Sellers, another website developer, said the iPhone's online applications were useful for business. "Every product we use is web-based, like collaboration tools and email," he told ZDNet.co.uk.

Although the software development kit (SDK) for the iPhone is yet to be released — severely limiting the number of available third-party applications — several software companies have declared their products to be iPhone-compatible because they are web-based.

The only aspect of the iPhone that did not impress Sellers is its lack of 3G functionality. The device only works on O2's slower Edge network, which will only cover 30 percent of the country by the end of this year. When outside Edge coverage, the device will fall back to the even slower GPRS network.

"That's the only backwards step here," said Sellers, who currently uses Windows Mobile but is looking forward to the iPhone's bigger screen and better browser.
