Social networking website StumbleUpon released their Android and iPhone App. Download the free app and log in with your StumbleUpon username and password. All of your StumbleUpon preferences will automatically load on your phone, so go forth and stumble! You can stumble all topics at once, just like on your computer, or stumble in a particular topic. It’s really easy to to stumble in some of the most mobile-friendly channels we have: Photos, News, Flickr and YouTube. In addition, you can share your favorite sites directly to other Stumblers and via Facebook, Twitter or email.
The new StumbleUpon app is optimized for the mobile discovery experience and uses the same personalized recommendation technology users would encounter using their personal computer or iPad. Through their mobile phone, users can ‘thumb-up’ or ‘thumb-down’ sites they like or dislike, and preferences are saved for their next session when they open the app.
Users can narrow their stumbling to a particular category, such as Photography or Science, or browse through pages in no particular category. They can also view content on best-in-breed content sites, flipping through lush photography on Flickr or funny videos on YouTube.
The free app is available for download from Apple’s iTunes store here or through the Android Market here.
I’ve by no means been huge but I have to confess that the iphone is kind of good!
I would wish to know if this concern about the iphone 4 is important or not. I’d like to purchase the brand new one and I was wondering if the calls truly drop more or not. Sorry if it’s kind of off matter 
Thanks a lot
