Can I update iPhone 4 to iOS 6.1?

I have an iPhone 4 and have waited to upgrade it to the new system. I had just heard about how it takes up a lot of room and how it had battery issues. I don't get great battery life anyways so it probably isn't that big of a deal. Should I upgrade?

Added (1). I'm on 5.1.1

IPhone stuck behind radiator?

Don't ask how, but I managed to get my iPhone stuck down the back of my radiator. The brackets go all the way up the sides, so know chance of getting it out that way. I can stick thin things up the bottom and move the phone, but nothing else really? Any easy suggestions?

Does an iphone 4 8gb have enough space?

I recently broke my iphone 4 16gb and I want a new one but my mom doesn't want to spend as much money. I never looked at how much memory I had used up before I broke my last phone but I assume I didn't use too much.anyway I really don't ever have videos stored to my phone, I will say I take as many pictures as any average 16 year old (plenty and plenty), and I may have one or two albums stored to my phone if that because I usually listen to pandora. The only apps I use are twitter, instagram, pandora, and maybe a few (not many at all) games… I also download apps out of curiosity all the time but I never keep them for more than like twenty minutes unless I find that they're super entertaining (which rarely ever happens), therefore the only ones that permanently stay on my phone are like I said before instagram and twitter and pandora.

If I get a replacement iPhone 5.will it be refurbished?

Right… So I got a 32GB iPhone 5 for an Early Christmas present (On SIM Only) in November from my grandma and grandad. It was early because my mobile contract at the time was approaching the end.

It was ordered from the Apple Store online and arrived in good condition. The only issue I'm having, is the battery draining. I took it into the Apple Store yesterday (Saturday 9th Februay 2013) and the guy assisting me did a health check on it, said my battery was fine so it was clearly the software. I thought to myself anyway it was a software issue because it sometimes crashes when I pull down the notifications centre.
And so the guy did a deeper system reset and said that should be fine. Problem being that it hasn't corrected my issue. I'm going to try it these next few days see if it is better but it hasn't been so far, and if there's an issue, then we will take another visit next Saturday where they will probably offer an exchange.
I'm just wondering if it would be a refurbished model or would it be brand new?
