Information The Technology

Since its beginning in the year 2007, iPhone has carved out a huge market for iPhone development. iPhone application development has become very important for the companies working on various mobile development platforms. With the iPhone SDK available, mobile developers can now build new apps and also customize the existing ones.There are two types of iPhone apps, web applications and native applications.

iPhone is the fastest growing and most popular platform for mobile development compared to other platforms. More and more mobile apps and web development companies are going for iPhone development having understood the huge market that it caters to.  Some of the popular categories of iPhone apps are, iPhone games, iPhone maps, iPhone m-commerce apps, e-book apps, social networking apps, and lot of other entertainment applications.

Your iPhone developer must have years of hands-on experience in iPhone apps development and must know what are the common challenges that come along during the course of development.

Restrictions on iPhone Application Development
As an iPhone application developer you may find iPhone to be an ideal platform or device/gadget to develop a killer application to sell and make a good fortune. There are some restrictions laid by Apple, producer of the iPhone, which may have negative impact over your development plan.One application at a time
The first restriction put by Apple is "Only one application can run at a time".This means if you are surfing over the Internet and some one calls you, then you have to quit the surfing to attend the incoming call.

Suppose you have developed a GPS application which needs constant support from the user to collect a particular data for your geo-location, then again it makes a compulsion for the user to continue with the same application and ignore all important calls for you. This makes the implications of that application vague.

No third party in background
Another restriction is "no third party application will run in background". Even the whole class of such application will prove useless or significantly less useful than they otherwise would be.

Control on apps
Apple store is formed for the centric distribution of the apps. None can directly distribute any apps and one has to come at the Apple store for its marketing purpose. It not only acts as a marketing point for the developers but can prove a gateway for the iPhone application developers.
You have to take permission for the entrance as an iPhone developer by registering with Apple.

Revoking the certificate
Apple can exert vertical control over the iPhone application developer by simply revoking the certificate given. You are right but you may know that since Apple forces all legitimate iPhone apps to be signed, if the certificate is on the "revocation list" no apps signed with that certificate will run anywhere. No support for previous versions

"Applications targeting iPhone OS releases prior to 3.0 beta cannot be tested in this seed"
"This software should only be installed on devices dedicated exclusively for iPhone 3.0 beta application development"
"Devices updated to iPhone 3.0 beta cannot be restored to earlier versions of iPhone OS"
"iPhone SDK for iPhone 3.0 cannot be used for submitting iPhone OS 2.2.1 applications to the App Store"
If you are an iPhone developer, you'll need two development machines and two iPhones to be able to work on your 2.x OS-based apps while checking out and upgrading code for the 3.0 OS.
