Where can I get a case that is also a battery for the iPhone 4?
I have seen ones for previous versions of the iPhone - is there one for the new iPhone though?
Solution 1:
Not yet, but I found a couple that are soon to be released:
iPhone 4 Fuel Max
EXOGEAR iPhone Battery Case
Solution 2:
I've been very pleased with my mophie "juice pack" for my first-generation iPhone and the "juice pack air" for my 3GS. I recommend waiting for mophie to ship a battery case for the iPhone 4. You probably won't have to wait very long—I'm sure they're eager to tap the already large and fast-growing market of iPhone 4 owners.
