Is there an app that can recharge iPhone?

My job requires me to spend a lot of time far away from any kind of power source including a vehicle. I find my iPhone ends up dying about half way through the day. I heard that there are apps for about anything. Is there an app that will recharge my cell phone? Maybe make it solar powered or something.

Which size Iphone should I purchase?

I currently own an ipod at the moment and I hoping to purchase an iphone. I have about 150 songs on my ipod.around 200 apps. 250 photos. And 25 videos (around 5 movies and a few less than 10 minute videos). I'm thinking I'm only gonna need a 16gb but I worried about not having enough space if I decide to put more stuff on there. Do you think I should just get the 16gb? Also, does anyone know of an online calculator where I'll be able to put in my details about how much stuff i'll most likely have on my iphone and see what size iphone i'll need? Thanks.

Does T-Mobile support unlocked iPhone 4s?

My carrier is T-Mobile. I'd really like to purchase an iPhone 4S, though. I've even considered terminating my contract with T-Mobile due to their stubbornness to carry iPhones in their product lines (which I think is detrimental to their market share).

My question is, does T-Mobile USA support unlocked iPhone 4S phones? If I bought an iPhone 4S, would I be able to text, call, and browse the internet on it like I could with, say, Verizon, AT&T, or Sprint?

I'd also like to know, if I can use an unlocked iPhone 4S with T-Mobile, would I be able to use my unlimited data plan/wireless hotspot plan (under T-Mobile) on my iPhone 4S?

What are the setbacks of unlocking an iPhone with T-Mobile?

Any answers are appreciated.
