How to hard reset iphone 4 without passcode or iTunes?

I forgot the password on my iphone 4, so I'm willing to reset it. I looked around the Internet but most have something to do with iTunes, but I don't have access to iTunes. How can I reset my iphone with just the phone and nothing else?

Why does the iphone camera make me look ugly when the flash is off?

When i take pictures of myself with an iphone without the flash on i look so bad my forehead and nose look bigger my eyebrows and whole face look uneven my under eyes look darker and i don't look anything like i do in the mirror, but if i take a picture w the same face in the same position it looks 10x better. Why is this?

Is it possible to uninstall IOS8?

I've downloaded IOS8 on my iPhone 5s, and my mother has downloaded it onto her iPhone 5s too. Both phones are now incredibly slow, almost to the point where they can't be used. The screen freezes, apps don't respond, it sends texts while I'm still writing the message, and I can't answer calls. Both phones are only two months old and have never been dropped or damaged in any way. I didn't install it on my old iPhone 5, and thats working perfectly. Is there any way to uninstall it?

Procedure for switching to a new carrier and number transfer?

I'm planning to switch my cell phone plan from Rogers to WIND. I'm just asking what the procedure is to do so.

My Rogers plan is not under contract and the phone I use is iPhone 4S. I'm not sure what to do first. Do I go get the WIND plan first from the store an then call Rogers to terminate? Or should I call Rogers to terminate the plan before I go and get a new plan from WIND? How would I be able to transfer the number to a new carrier and continue using the same number? FYI: I live in the GTA.

I'm switching to the $35/M WIND plan with unlimited calling/text/data. I pay over $60+ to Rogers for the same plan but with like 2GB of data.

IPhone 4, is it still a decent phone to get?

I want to buy the iPhone 4. I had the 5C but Sprint service sucks! I can get the iPhone 4 with AT&T

Do the camera take clear pics and what all can it do that my iPhone 5C can?

* Only comment if you had either phone and know about iPhones please!
