There is an indication that Apple would soon implement multi tasking feature on the iPhone. The main concerns that held back Apple from introducing this feature is memory limitation and the draining of iPhone battery. At present you cannot run multiple applications on the iPhone. One basic feature missing on the iPhone, which you find even in low cost mobile phones is live call recording. There are many voice recording applications for the iPhone that you can use for recording audio, but sadly not call conversations that you’d love to record.  

With the introduction of multitasking feature, there would be background processes running on the iPhone. However, this is still a rumor as Apple has not provided any hint on this line. The need to introduce this feature comes from the speculation that Palm Pre the device considered as a threat to iPhone has this. 

With a limited temporary memory of 128 MB and a 412MHz ARM processor, it would be hard for the first generation and the present 3G iPhones to support more than one or two background applications. In view of this, there is a possibility that the feature might be implemented with a restriction on the number of apps that can be run at a time. For this limitation, it’s also possible that background running process might come with the next iPhone revision if Apple is looking for a 100% multitasking feature. 

Based on the product cycle followed so far for the iPhone, analysts believed that the next major iPhone revision would come in either June or July 2009. The 32GB iPhone which has been expected for so long now could also be coming in the next revision.
