SameCell has a had a significant upgrade today, now packing tabbed browsing, event and location features, and including some extra functions if you happen to have GPS. Of course, the SameCell’s really great if you don’t have GPS, since its location-based services are all based on cell tower recognition. In fact, SameCell was the very first app I saw that use the technique, and since then Google Maps and even the BlackBerry Bold has started doing the same thing. They’ve also got a cool program where you get paid for discovering new cell towers not in their database. The core functionality of being alerted of buddy proximity remains – the only trick is getting your friends to install the app on their BlackBerrys. Go ahead and check out the new features or head on over to www.samecell.com/setup on your Browser to get started.
