Does anyone have answers to my two previous questions re: Cardo Scala 500?

1. do I need additional software to use this headset with Skype on my new Dell D610?

2. can i use with my blackberry 7100t ? - from T-Mobile: This is one sweet little phone loaded with all of the cool features you want, like Bluetooth® connectivity, speakerphone, and downloadable ringtones. Plus Web surfing on a big color screen. i don't need anything else, right?

thanks,

sam
