Slashgear brings news that there is now a VoIP app in the Apple App Store for the iPhone (and iPod Touch) which allows IP calling over 3G networks.

The software, known as iCall allows for incoming call notification even when the application is not running.

This signals a lifting of the 3G VoIP calling restrictions which Apple imposed on iPhone apps.

Truphone who provide a SIP standard voice over IP calling system for mobile handsets of the Symbian S60 platform as well as some iPods and the iPhone have announced that they will now support Paypal payments for customers using iPods and iPhones.

While a number of debit and credit cards were already accepted, customers will now be able to use Paypal through their device to add land-line calling credit without the need to resort to using a web-browser equipped personal computer.
