Just wanna say thanks for all the help guys. I've made three different posts over at the Droid subreddit at reddit.com and got no responses.
iowa: airdroid works, but it only gives me access to the sdcard filepath. Even Astro gives me more than that. Nothing new pops up under my computer by the way. I guess I should have included that before.
My PC recognizes every other device I connect it to except my mom's phone. I tried her Vivid as well and it has the same problem. I have a laptop I can try connecting it to. I'll update this post with the results.
Again, thanks for the help.
"Key question: Did you get your ICS update by way of OTA?"
Mind explaining in simple terms what this means? I'm experienced with computers but pretty new to smart phones.
