Are all AC adapters the same size?

I have a Brookstone Iphone dock/speakers that is not sold anymore, and the power adapter is broken. I'm going to buy another one, but I'm not sure if it matters which one to get. First of all, the plug for the adapter itself says AC adapter, but on the speakers themselves, it says input: DC. I have tried a couple of adapters that I found around my house that look very similar, but the size is slightly off, so they do not fit. The current adapter I have says Output: 10V==3.4A. Will any 10V adapter I get fit the speakers or will I need a specific size? Also, what is the difference between and AC and DC adapter and which one should I get?

How to I fix my iPhone headphone jack?

One day I was going out and my phone was dead so I decided to charge it in my car. It was an old car by the way and so we had cords that allowed us to play music from my phone and also to charge. I was showing my dad a new song and plugged the cord into the headphone jack but the music wouldn't play. After awhile I decided to put the headphones on and try to play music and I did but it sounded far away if you know what I mean. So I'm guessing the cord really jammed the headphone jack and I had no idea it would mess up my phone. Kinda affected my charging part alil but not as bad as the headphone jack. What can I do? It sucks not having music in my ears! Also Apple is charging $270 to fix which us very ridiculous! Any advice?

My LDB hasn't texted me in a week?

Ok so I have a long distance boyfriend and me and him usually text like everyday but now it's been about a week since we last talked. Now the thing is, my phone doesn't have service right now but I have an iphone and he does to but can't two iPhones still like iMessage with Wi-Fi even tho I don't have service? Cause I'm worried that maybe he has tried messaging me but I haven't got the messages bc of no service and I don't want him to think I'm ignoring him or has he just chosen not to text me? If we can text with no service than I really don't want to text him first or maybe is he waiting on me to text first? I don't know I just need some advice. In really worried and I know i'm probably freaking out too much over this but I really like this guy and we have an really good relationship. But please, what should I do? Don't say anything like long distance don't work cause it can If both ppl try hard enough for it to work!

Uncooked rice grain wedged in charger port iphone 5s?

I tried the rice trick on my wet iphone, the phone is now working fine except a piece of rice is wedged RIGHT at the bottom of the charger hole. Tweezers, knife, pin, vacuum cleaner are not able to get it out. Will Apple be able to get it out because I can't even see the grain of rice anymore and the charger does not work.
