I have blogged previously about the open source Piwik web analytics software package, which enables webmasters to keep track of visitors to their web sites, including where those visitors came from, which search engines referred them, what keywords they typed in, which other web sites referred them or what marketing campaigns drove their traffic. In short, it's a great little utility and a worthy rival to Google Analytics.

There are two simple methods of capturing screenshots of the iPhone.
The first method simply involves pressing and holding the home button by pressing the power button once. An image of the screen will be saved to the Photos folder automatically.

The second method involves downloading and installing the iPhone SDK from the Apple Developer web site.
Once installed, load the XCode application:

It is already possible to run Windows on Mac computers, either by booting into the operating system via BootCamp, or by running a virtualised machine image using tools such as Microsoft Virtual PC (for PowerPC Macs) or Intel-based tools such as VMWare Fusion and Parallels Desktop. Applications can even be run in individual windows on the Mac desktop without the need to see the entire Windows desktop.

OpenVPN is a free, open source SSL-based virtual private networking solution that I have posted about previously (http://blog.brightpointuk.co.uk/openvpn). Although it is possible to configure access to an OpenVPN server from a Mac manually, and there are free GUI-based clients available, such as Tunnelblick (http://code.google.com/p/tunnelblick/), these require that you create the connection script manually and have a working knowledge of how the OpenVPN server has been deployed.

MacOS 10.6, or Snow Leopard, features an integrated Cisco VPN client, able to connect to an IPSec Cisco VPN appliance.

To configure the VPN client, open the System Preferences and select Network. Click on the + symbol to add a new connection:

Select VPN as the Interface type, and Cisco IPSec as the VPN type. Enter a name for the connection and click Create:

As has already been much-publicised, MacOS 10.6, or "Snow Leopard", can access Exchange 2007 mailboxes to provide integration with the Mac's native email, contact and calendar applications: Mail, Address Book and iCal.

Only Exchange 2007 is supported, not Exchange 2003, and only Exchange 2007 servers running SP1 update 4 or later. At the time of writing, the public release candidate of Exchange 2010 appears to work fine.

The iPhone Configuration Utility allows the administrator to define common settings governing password policy, Server ActiveSync, certificates, wireless access points, VPN connectivity, LDAP access and more in a single configuration file and deploy those configuration settings to any number of iPhone devices.

Version 3.0 of the iPhone operating system is now available for download from Apple. This latest release of the OS brings several new features including MMS support, Copy & Paste, Search, USB tethering (modem usage), among others. But what about for the enterprise: will this latest OS make the handset more attractive to system admins who until now may have preferred Windows Mobile, Symbian or BlackBerry?

It is not possible to use an iPhone until you have first connected it to a PC that has iTunes installed and run through the activation process.

iTunes will then run the user through a wizard which will activate the device for service (the same also applies to the iPod Touch).

If the iPhone is being rolled out across a business, this means that the administrator must decide whether to install iTunes on each iPhone user’s PC, or activate all devices themselves on their own PC with iTunes installed.
