There has been no shortage of extra juice packs for the iPhone 4 with Ballistic, iLuv, iKit, AGF and Scosche releasing their own products and announcing support for the Verizon’s iPhone 4, But here’s the news: Mophie has announced it’s one of a kind juice pack which works with BOTH the AT&T and Verizon iPhones. The juice pack “air” is set to reach selves by the end of this month. The first few shipments would be black with silver accents while soft-touch red and glossy white versions are set to release later. Still with a steep price of $79.95 it’s pretty expensive but every 3G user should have one.
