I probably should have mentioned this before, I’m just to used to not being listened to, you will need some third party software to take advantage of all the Treo’s capabilities. If you were anyone else I would just zip’em up and email ’em to you. However, I can tell you about them. You should be able to download the basic pocket tunes (mp3 player) for free when you register the Treo online. The upgrade allows some extra functionality with regards to playlists and such, but most likely not needed. The software for playing ringtones is available from http://www.toysoft.ca . It�s called lightwave. You can get the personal recorder software there too. I would recommend the ringtone software only if you are one to use the polyphonic ringtones; then it is far superior. However, some people find that they do not like music for ringtones, they like ringtones for ringtones. It takes getting used to. At first my phone would ring and start playing music, then I would think to myself, hey I like that song, where is it coming from. The most enjoyment however, is just the idea of using music that I already paid for, but at the same time not paying twice for it, just to play it on my phone. Another revenue stream gone dry.

The next must have accessory is the Seidio 2 in 1 Headset for Treo 600.

The 2 in 1 Headset for Treo 600 (Patent Pending) is a hands-free device and also doubles as a set of headphones. The headset comes with a microphone, a one-touch button, and an in-line music and phone volume control. A switch is available on the control console to allow you easily select either “Hands Free mode” or “MP3 mode”.

With this headset, there is no longer the need for an additional adaptor to plug your headset into the Treo. It has been designed to plug directly into your Treo.

This single headset allows you to do a variety of things such as listen to MP3 music, be alerted about an incoming call, answer and hang up calls with a one-touch button, and adjust sound volume.

If you are a true audiofile an adapter that allows you to use high end earbuds is also available.

This model allows you to plug any pair of 3.5 mm headphones into the 2-in-1 headset adapter. Now you can talk on your Treo600 and listen to MP3 music with any 3.5 mm headphone of your choice.

Both headsets offer retractable versions.

I would also recommend getting a 512 mb SD card. The price has dropped dramatically and you should be able to get one cheap at Frys.
