GSPlayer
Your cravings for soul stirring and foot tapping music will be taken care of by the GSPlayer. This nifty little software is effective and easily manages all your MP3s and the sound quality is good enough to please the finickiest-of musically toned ears. And if you don’t happen to be much of a fan of the very practical (and boring) basic blue look, then jazzy, flashy skins are also available to please your eyes along with your ears.

Skype for Pocket PC

The best part about mobile telephony is that one doesn’t need to have a phone to use it. This is exactly what makes Skype ideal for all wireless enabled smart phones. If you’re using a smart phone, it’s still a lot less expensive to make an international call using Skype than making a direct call.

Kevtris

Kevtris is almost like Tetris but with an extra hurdle and help. The addictive Tetris-like game adds an extra aid and extra hurdle. Some of the difficult guess work is removed by the shadowy placeholders, by helping you in figuring out where the pieces will fall but navigating the pieces with the small buttons of your phone will be challenging enough to keep you hooked to the game.

Spybot - Search & Destroy

As malicious viruses have now started targeting mobiles, cell phone security is one basic area that you just can’t afford to skip. The Spybot – search and destroy is an excellent free software that will protect your smart phones and pocket PCs from all intruders.

Acala 3GP Movies Free

One of the biggest perks of having a PDA is being provided with full-on entertainment. The Acala 3 GP program is a software that is capable of converting almost all kinds of video files into the 3GP format to play on your mobile phone. Just get yourself some popcorn, some coke, a hot dog or two and lie back and watch some great movies on your phone.

Magic Button

Wouldn't it just be great if you could switch off your pocket PC with the push of a single button? It does sound great and you too can do it by installing the Magic button on your smart phones. The magic button allows you to easily control all mobile programs and also increases your work efficiency by letting you create a version of your mobile’s hardware buttons. Sounds cool, doesn’t it?

Tone-This

The fact remains that most free ringtones (and sometimes the paid ones as well) sound so horrendous that they remind you of the title track of a C-grade Bhojpuri movie. So why shell your precious bucks for a ringtone that you will shudder to use in public. So, instead, use the ToneThis software to produce one on your PC and transfer it to your phone.

Google Maps

No matter how great your direction sense is, there will be occasions when you will end up losing your way. But fear not, with the Google map application, your phone will help you find your way no matter how hopelessly lost you are. Though the program doesn’t have a GPS sensor which will actually pinpoint your exact location on the map, but then again how much can you expect from a free software!
