Oh sure, VoIP on the iPod touch is hardly breaking news these days, but what if you could actually slap on a regular SIM card and make calls on said device? That's what Yosion's appropriately named Apple Peel 520 claims to do. Powered by an Infineon baseband chip, this adapter not only offers voice calling and text messaging (presumably requiring a jailbroken iPod touch for the apps; GPRS not possible yet), but it also doubles up as an 800mAh battery and provides 4.5 hours of call time or 120 hours of standby juice. We're told this cheeky hack's coming out in China as early as this week for somewhere between ¥300 ($44) and ¥500 ($74), although the lack of an official website, full spec sheet or compatibility list means we'll have to remain skeptical with this potentially vaporware company. Maybe the demo video after the break will keep us believing.
