Stay alive, iPhone 4/4s! I got stuff I needta say! 

What's runnin' yo phone while yo runnin' yo mouth? Yo battery tha's what! But yo battery can only run yo phone so far 'fore it start runnin' outta power and then yo runnin' yo mouth to no one and then you all like, "you hurd what I said?" and it's all like ____________ (that's the sound of nothing), understand?

That's why yo gotta grab this uNu iPhone 4/4S Battery Case. It protects yo phone while it powers yo phone longer than ever befo' so when you like "you hurd what I said?" and they like it's all like ____________ (that's the sound of nothing) it's because they hung up on you cause they're tired of you always runnin' yo mouth.

Least in my case, that's how it is.


(Another quick tangent: if there are any science-y people out there with experience turning liquids into fabrics, please send me a personal message.)

And the best part: this thing's cheap. That's right; it gives you 5 hours of talking and browsing time (7 hours of video; 28 hours of music) and it comes in under 30 bucks WITH shipping! High quality AND low cost? Sounds like someone gave uNu the resources they needed to really perfect their product!

(Final tangent: Anyone know any billionaires looking to back an ambition project? Power in the coffee and/or textiles industry a BIG plus.)
