People you know have spent small fortunes on shiny new smart phones such as the iPhone 3GS, a BlackBerry or the Droid. But the devices still don't have all the features they want.

The battery runs out too quickly when they surf the Web, watch a movie or play a video game. They wish the phone offered turn-by-turn directions like a true GPS unit and without monthly payments. A tripod would come in handy when they want to take a group photo on the phone for Facebook.

All these holes can be filled by accessories that make for good gifts. We've got some suggestions.

TomTom for iPhone Car Kit, $119.95

This new kit from TomTom Inc. makes the iPhone easier to use for in-car navigation. The kit includes a mount _ allowing you to attach the phone to a window or the dashboard _ and a car charger.

In addition to this kit, your recipient would need a GPS application on the iPhone _ TomTom sells one for $100, with no monthly fees.

Pros: The TomTom mount is sturdy and grips the windshield tightly. It tilts forward and back, and rotates for viewing street maps in landscape mode, if you want a wider angle. The mount has a built-in GPS receiver to boost signals, a speaker for louder driving instructions and a microphone so you can take calls handsfree. The mount also charges the iPhone and has a line out for music playback.

Cons: There are cheaper GPS apps and third-party car kits on the market.

Where to buy: Apple.com, TomTom.com and Apple retail stores.

Mophie Juice Pack Air for the iPhone, $79.95

It's an iPhone case that just about doubles the life of the phone's battery as well. The phone charges through a connection port embedded in the case.

Pros: I like the battery indicator lights on the back of the case that tell you when you're about to run out of power. It has a standby mode, so you can use the Juice Pack battery only when needed. You can charge your iPhone and the battery case at the same time. It handles 500 full recharges.

Cons: The top of the case doesn't curve over the iPhone screen, making me worry that there's less protection if I drop my phone face down.

Where to buy: Online and various retail stores.
