This will arrive on Tuesday, according to CNET. It requires a Wi-Fi signal (chat will work over AT&T’s network) and iPod touch users must use a headset with a built-in mic. The UI resembles a native iPhone app, as opposed to Skype for Playstation Portable, which looks like the desktop version of Skype.
This will do two things. First, generate a boost to Skype, as iPod touch users will gain telephone functionalilty. Consequently, apps like Fring will struggle to compete with Skype’s well-established user base.
Kudos to Apple for approving this, in spite of the Wi-Fi limitation.
