Websites and web apps can now behave like native iPhone apps, with great network integration. 
 iPhone in Action is an in-depth introduction to both native and web programming for the iPhone. You'll learn how to turn your web pages into compelling iPhone web apps using WebKit, iUI, and Canvas. The authors also take you step by step into more complex Objective-C programming. They help you master the iPhone SDK including its UI and features like accelerometers, GPS, the Address Book, SQLite, and many more. Using Apple's standard tools like Dashcode, Xcode, and Interface Builder, you'll learn how to best use both approaches: iPhone web and SDK programming.Other authorsSee publication

      RFC 2245 - The TLS Protocol Version 1.0IETF.ORGTLS is the standards version of the most widely deployed security protocol in the world, SSL. 
 TLS, meaning “Transport Layer Security”, is the protocol that is used for establishing a secure connection between a client and a server, typically but not exclusively for web connections to internet commerce shopping carts, credit card companies, etc. Protocols such as HTTP, SMTP, POP3 and others use TLS to create secure connections.

 TLS, meaning “Transport Layer Security”, is the protocol that is used for establishing a secure connection between a client and a server, typically but not exclusively for web connections to internet commerce shopping carts, credit card companies, etc. Protocols such as HTTP, SMTP, POP3 and others use TLS to create secure connections.
 TLS is able to authenticate both the client and the server while it creates an encrypted connection between them both. The TLS protocol is extensible which means that new algorithms can be added as long as both the server and the client know about the new algorithms. TLS is meant to be a replacement for Netscape's original SSL protocol.Other authorsSee publication
