I’ll confess that I don’t compose a ton of calls on my mobile phone, and generally don’t distress about how many minutes I’m using. However, there are those out there that talk considerably more than I. For those folks I give you iCall.

iCall is a useful application which will allow you to instantly switch within VoIP and GSM calls. that means you can sit at home and use your

local Wi-Fi network to form calls without using up valuable minutes.

No, the iPhone won’t be the first phone to take advantage of that sort of feature, but you can bet that it will be one of the more useful apps. that is said to already have passed the Apple inspection, and should hopefully seem on the App Store sometime after launch.
