About to Get a Mogul...What Programs Should I Get?

[skinsraj28]

There seems to be a ton of posters here who know a lot about the Mogul and phones/PDAs in general...so I figured I'd pose the question to you all.

I'd love suggestions for what I should download...so if possible, could you respond with answers to the following questions:

1) What program?
2) What does it do?
3) How do I download and install it? Link to find the download?
4) What, if any, existing program will be unnecessary once I download it? And can that unnecessary program be deleted?

I've never had a PDA, so any and all suggestions are welcome. I'll be using the PDA predominantly for calls, web-surfing, and messaging.

Thanks in advance, I appreciate you taking time out to help me.
