Then what? 
Then you can research, place and modify reservations at HandRes. 
You will be able to book a Commercial flights, Chartered air flights, Hotel rooms, Rental cars, Broadway shows, etc... from virtually anywhere within coverage of your wireless data provider. 

What hardware do I need to use the HandRes service? 
You will need a PDA (personal digital assistant) or palmtop, a wireless modem for that device, and a wireless data service connection. It doesn't matter what company makes your device, just as long as you can attach a wireless modem to it. It is even better if it is built in already. 

What software is needed to use the HandRes service? 
Any internet browser for your handheld device will display HandRes content, but you should use a browser that supports SSL (secure sockets layer) to enhance your security.  

What kind of modems are available? 
If your palmtop device supports a PCMCIA Type II port, the AirCard 300 by Sierra Wireless is highly recommended for these devices. 

Palm O/S PDAs are usually given wireless connectivity through the use of "cradles" - modem which snap onto the PDA. Palm Pilot and III devices may be cradled onto a wireless modem using Novatel Wireless' Minstrel series of products. The Palm V PDA may also be cradled onto a new compact device called the Omnisky modem. 

Standalone modems such as the Novatel Wireless SAGE and other OEM products may be connected to any type of computer, palmtop, or pda. You will need a serial cable for your PDA to connect to these modems. 

Finally, some devices contain integrated wireless modems, such as the Novatel Wireless Contact.
