Should I get my iPhone battery replaced?

When I plug my iphone 3gs in with the wall charger sometimes it won't charge. There will be no vibration or chirpy sound or the thunder symbol inside the battery. I have to keep unplugging it and plugging it until it vibrates meaning it is charging. Is it a bad battery that's causing this?

My Iphone 4S dropped in water what should I do?

Okay so last night I fell into the pool in a very stupid way and my iPhone was in my pants pocket, after 2 seconds I got out of the pool, it was on and working but I turned it off, dried it and only turned it back on today, it was all working BUT my flashlight is on 24/7(even when the battery dies) and my back camera is not working, what should I do? Should I go to apple store and talk to them? I've heard they won't do anything cause of that water dot sign that indicates it had water damages, but I did some research and if I rub some bleach on it, it will go white again, also so I just continue to use my phone? Or should put it on rice or something like that.

I'm thankful already =D

Do I really need Otterbox Defender for iPhone 5?

Or, would a Commuter do justice? It isn't really a matter of cost, just bulkiness. I do not want my beautiful iPhone to be hidden by the Otterbox completely. I'm upgrading to an iPhone, and have had an iPod touch for a year. I have dropped it only once where damage was done. It didn't have a case on at the time, and I was taking a picture of the concrete (don't ask). A few times (maybe 3, 1 for sure) in the morning I was making my bed and when I "puffed" the blanket in the air it flew across the room (I have carpet).

Is it safe for me to update my Iphone 3GS on ios 4.1 to ios 6?

Hi, I have a Iphone 3GS on IOS 4.1 (8B117). I bought it slightly used from someone. The phone already has Cydia (1.1.6), Installous and WinterBoard installed. But I want to update my Iphone to IOS 6 because on 4.1 I can't get many apps because the ios is too old. The person I bought it from claims that it is unlocked. She had Verizon and it worked and I have fido and it works. I have not yet rebooted my phone. So the main question is: Is it safe for me to update my Iphone 3GS on ios 4.1 to ios 6? Thank you so much!

Added (1). What should I do next? If it is going to lock again on previous network, can I use redsn0w or something to unlock it from IOS 6?
