My favorites are: locale: Great app! It made my Hero much more smart. It switches to flight mode itself every night at 11pm, and switch back on wifi in the morning. It turn off wifi and become silent everyday when I reach my office or cinema, and it turn sound back on when I am back home. Such a nice app! Handcent Sms: Best text app in the market. iReader: .txt version e-book reader. Very easy to set up and use. I choose this over aldiko simply because I have access to a lot of txt version ebooks rather than .epub books. However I did have some issue with the "go to .." function with large txt files over 3M. Dolphine Browser: Lovethe gesture feature. My days: The app all girls must have! Astro player Beta: My fav player app. Although It still has a LOT (really a lot) to improve, there are some features that other player don't have. iMusic: search and download music for free. k-9 mail: support IMAP push mail, and is free! Where is my droid: Very useful app for someone like me. Send a special text message containing "attention words" to your phone, and your phone will ring really aloud even it was at a very low volume or in silent mode to let you know where you left it. wordup: I am addicted to it now.
