A version which is friendly to the average consumer may be a long way off, but what a breakthrough this could be...
Coder 'eok' in his blog has this week claimed to have made the holy grail of iPod touch discoveries: VoIP.
As you might expect - despite providing numerous screen grabs like the ones above - actual hard facts about the find remain extremely thin on the ground. What we do know however is that eok claims to have established sip communication and coded the touch's keyboard to appear, enabling the typing of contact numbers/addresses.
At this stage however no audio (either incoming or outgoing) works though unrelated hacks do claim to have commandeered basic control of the touch's allegedly disabled mic (a leftover from its iPhone skeleton) meaning a standard mic/earphone headset could theoretically work for calls with connectivity provided via WiFi.
Of course vital aspects such as a user friendly GUI and information about how this affects battery life amongst many others are all required before we can toss away our iPhones, but as interesting discoveries go this one is right up there.
In related news, a second intriguing and potentially far more immediately useful hack has been developed for the iPhone this week: MMS. Yes, this outrageously overlooked feature now finally makes an appearance thanks to 'Tommy' and is available via Installer for unlocked iPhones. Current limitations for version 0.1 are only images can be sent and MMS messages cannot be received. A user must also enter their own MSS settings in the app.
Still, it's progress and nah-na-na-nah-nah to all you locked and contracted types...
