I have a Zio for use with Cricket.. The drivers are not that hard to find.. you can get them from the cricket online help site, the ziobykyocera.com site, or a couple other places. The problem is that even after installing the 'drivers' and the 'futuredial' application (which is a bloated contact manager app) -- you're left with crap on the computer that you don't need & when you connect the phone, it always wants to look for drivers from the windows website. It cannot find the drivers, and results in a message something like "unable to find the file specified" then it will tell you your device might not work properly.. There is a simple solution to this (a few actually)..here is what I came up with:
1) drop the phone on a concrete slab, and stomp on it until it is unrecognizable..
or
2) cram it down the throat of your nearest cricket stores' representative when they ask if they can 'help you'...
or
3) hit cancel when it tries to find drivers, click cancel again when it asks about the next device it finds, and finally click cancel for the third device it finds.. next on your phone (__with it connected__) go to usb ( I use the top bar, to get there.. ) & click where it says "select to copy files to/from your computer" & finally click where it says "Turn on USB storage". Finally your zio memory card will show up as a drive, from my computer.
STUPID Windows!! STUPID STUPID STUPID... it needs NO drivers..
