1. ) How can I transfer files ( non -music/ video) from my computer to my Windows Phone 7
2.) Camera timer..,am I overlooking it? Please help.. Other than that I love WP7
WP7 doesn't natively support file transfer like a USB device. There is, however, an app for sale that will allow you to treat it as such. I think it's called "PC Connect" and goes for $4.99.
For file transfer the only supported free way is to e-mail things to yourself, however as I've posted in the Apps forum, try using Dropbox. You can install the Dropbox client on your PC and move files into it, they'll be sent up to the cloud which you can then access from your phone at Dropbox
