Worth it to buy iPhone 5 now?

I've had an iPhone 4s for almost two years now (it replaced a stolen iPhone 4) and I have had no problems with it aside from the occasional app crashes, and starting recently, the phone will freeze for a few seconds, sometimes to where I have reboot the device. Would it be in my best interest to wait until the iPhone 6 is released? Or just pick up the iPhone 5 when the price drops? (I'm not eligible for an upgrade for two years-- my brother used my last one) On the other hand, is the iPhone 5s worth the extra cash? I love iOS because of its simplicity and flawlessness (in my personal opinion!). I'm an avid "smartphone photographer" and I've been perfectly happy with my 4s's camera but ready to upgrade. I understand that some Android phones (e.g. HTC One) have amazing cameras, and I've done research, but Apple's operating system is definitely for me. Any suggestions?

Added (1). I'm perfectly aware and up to date on the new iPhone 5c and 5s and their specs. I have been religiously researching to make this decision. My question is whether or not the 5s is actually worth the extra cash for the new specs compared to those of the seemingly very similar iPhone 5.

Can I get my data back on iPhone 4?

I updated my iphone 4 (to the iOs 6.something something) using itunes last night and have since lost alot of data on the phone including contacts, photos, videos, apps and many many more. I didn't make a back up before I started because I did not know it was necessary.

Computer won't recognize iPhone 4?

Okay, so my friend had a Jail Broken iPhone 4.It was working fine until recently, the device totally crashed. It won't power on, it won't enter safe mode, and it won't enter dfu mode. When plugged into her laptop, itunes recognizes it, but says it needs to be restored, when attempted to be restored, it freezes about halfway through. HER computer recognizes the device, but mine won't. I offered to fix it for her, as I have experience with Jail broken devices. When plugged into my computer, I get the "a device has malfunctioned… Blah blah blah windows message" iTunes won't recognize it at all, and neither will my computer. I tried to manually install the driver, but I get "windows was unbable to update driver. Device stopped working (10). I'm at witts end with this thing, and she lives in new jersey, so I can't just have her come over with her laptop. How do I get my computer to recognize it?

What is the difference between the iPhone 5s and 5c?

The specs are pretty much the same so why would you pay £100 more just to say you are superior? I'm digging the green 5c as it's my favorite colour and the plastic will protect my phone because I always drop my phone.

IPhone 4S, bad esn, App Store?

I wanted to purchase an ipod touch 5, but I realized I could purchase an iPhone 4S with a bad ESN for a cheaper price. I would only want the iphone to use as an iPod touch, but would a bad esn inhibit App Store purchases in any way withan apple ID?

Added (1). The iPhone would have the same processor and screen resolution, but different size. Also same iOS support ending in 2015.

Do iPhones cost less in china and Japan?

This is probably a really stupid question but do iPhones cost less there? I don't know why I'd think this but I just thought maybe because china and Japan are so ahead of the rest of us technology wise that maybe they'd cost less because they have better phones? I don't know I could be completely wrong and inaccurate but I was just wondering.
