iPhone fringsters wanting to boost their fring talk time by up to 7hours a day, listen up.

Mophie.com is now offering via pre-order a new “juice pack” that easily plugs onto your iPhone 3G. “The Juice Pack is a rechargeable lithium polymer battery in the form of a non-slip, soft grip case” and the manufacturer says the juice packs will extend talk time on your iPhone by about 6-7hours a day.

Extend the time that you can use your iPhone 3G in these ways (additional hours):

• Standby Time – Up to 350 hours

• Internet Use – Up to 6 hours on 3G | Up to 7 hours on Wi-Fi (fring uses WiFi)
