Applications May Be The iPhone's Shortcoming: Page 2 of 3

Then there's the airplane scenario. Because they only work with a live Safari connection, third-party iPhone apps--unlike Google Apps, increasingly usable in disconnect mode thanks to Google Gears--most likely won't be available offline, at least not initially. An Apple spokeswoman says the offline availability of Web apps "has not been addressed yet."

"If you go outside of your strong coverage area, you will lose your online applications," says Robin Slomowski, a developer for Flock, maker of a Web browser for social networking.

Mathew Murphy, a technical specialist at IBM, helped Web-enable applications designed for IBM's Lotus Notes client. "The biggest complaint was that salespeople couldn't run the Web version of the application offline," he says.

What's more, because the iPhone will run over AT&T's Edge network, which is slower than broadband, Web-based apps won't run as fast as native apps. If they require a lot of server interaction, they will tend to be "slow and awkward," says Derik DeLong, a blogger on MacUser.com.

There are security implications, too. Apple hasn't demonstrated a VPN client for the iPhone, which means companies running iPhone applications may be forced to share internal documents over less secure password-protected Web pages.
