CAN I UPDATE iPhone 3gs to ios 6.1.3 or its just STUPID to even think it?

I have one iphone 3gs 32gb with ios 4.0.1 and i want to update it at newer version 4.3.x because some amazing apps don't work at old iOs so i make some searches how to do that but i let it and i send it at a mobile service and told them what i wanna do. But what i heard from them it sounds weird for me. He says i can't update this iphone for the moment bcs the jaibreak for iOs 6.1.3 haven't come yet. I said WHAT iOS 6.1.3 i don't think the old iphone 3gs can handdle the latest version on ios, he says no the 3gs had worked perfectly at 6.1.2 but you had to wait until the jailbreak for 6.1.3 will come, now i'm confused is 6.1.3 to much for 3gs or its ok to update i don't want my phone to go slowly I HATE THAT, if somebody know how to do update and jailbreak and sim unlock step by step please tell my i think i'm gonna do it by my self the servicer is not knowing nothing: S. :?

Speakers on my iPhone 4S aren't working! Any suggestions?

I think I might have gotten it wet, and I have it in rice right now. Everything else works fine, including when I listen to things on my iHome and with headphones. And on an unrelated note, I tried to put some headphones in the jack, and they work but don't go in all the way. I thought there was a piece of rice stuck in there so I used a paper clip to get it out. I looked with a flashlight and there's nothing except some white stuff that turns powdery when you squish it… If you have any suggestions please help because my parents won't let me get another one if this one gets messed up!

So we're going on an hour drive with him… I hate being in a small space with him, because when I'm just on my iphone or doing something he will just start staring at me. I tell him to stop, so he says okay then he just steels one of my things and says that I did something to him. My sister gets mad at me then my parents punish me. I'm sick of him.

Do iPhone apps work on a Nokia phone?

I'm probably getting a Nokia phone in a few months, but there are apps from the iTunes store that I would much rather have. The reason I don't just get an iPhone is because Nokia's tend to be more durable than iPhone's and I tend to be more clumsy than every other person on this planet. I was just wondering if apps from the iTunes store would be compatible with a Nokia phone?
