Hi,<p>I work at SeeMyWhere and might be able to help with your questions.<p>1. To get SeeMyWhere to work, you have to download Xtify onto your phone. We suggest you do that by visiting SeeMyWhere.com on your phone, clicking download, and following the instructions from there.<p>2. As currently implemented, SeeMyWhere allows you to view the location of anyone who shares his or her username with you and who has location updates activated.<p>3. We are planning to sync with Facebook and Twitter, but aren't interested in competing with Loopt. They're a full-blown social network where we're an extremely simple location sharing tool. Some will want all of Loopt's features, others will appreciate SeeMyWhere's simplicity.<p>4. Location sharing isn't for everyone. If you feel it's a step towards Big Brother, then services like ours isn't for you. However, others appreciate the convenience and interconnectivity SeeMyWhere affords.<p>5. Our software only works on Blackberry, Symbian, Windows Mobile, and Andoid phones.<p>I hope that clears up the questions that were raised. Feel free to ask further questions either in this thread or through our help link at SeeMyWhere.com.
