Will Blackberry Curve stand up to the Construction Industry?

[radarthepinguy]

Hello
I am thinking of purchasing a Blackberry Curve.
I work in the construction business and need to know hoe this phone will standup to dusty enviroments?
I am thinking of purchasing a Zagg invisableshield:
ZAGG | invisibleSHIELD | BlackBerry 8310 Curve Cases, Screen Protectors, Covers, Shields, Skins, Invisible Shield
Will this product solve my problem?
Are keys still easily used?
I also plan on buying a case and holster which will allow the device to be put in with keys and screen facing inward to give even more protection?
I have also heard dust is a major problem for the trackball?
Are they cleanable, exchangeable?
Thank-you for any advice.
