Would my iphone or speakers blow?

During tech in school i made speakers which are very very loud. That to keep the volume stop from blasting my ears i have to leave it on half-full on the iphone.

I have a feeling that my speakers will as they are tiny but would my iphone get damaged because of it.

IPhone 4 Sound & Volume Issue?

I have the original iPhone 4 I noticed the other day when I received text messages that it would only vibrate. I checked all the settings the mute switch was not on, in settings everything was set up for a normal tone. When I push the volume up and down buttons on the side of the phone it shows the ringer icon but there's no bar underneath it to show what the volume it at. Also there's no sound when playing games or music. The strange thing is when you call the phone it does ring. I'm not sure what is going on with it and I can't think of anything that can fix it. Any suggestions would help.

TWITTER NOT WORKING ON iPHONE

So, everytime I go to the home page on twitter, on my iPhone, it says, "Error loading tweets (400) tap to retry" it was working perfectly fine before, so why is this happening now? Even when I try going to people's twitter pages it doesn't let me see their tweets, or who they follow. I tried deleting the app and re-installing it again, but it still pops up like that.

Unlocking iPhone 4 on Vodafone?

Getting an iPhone 4 in a few weeks time from a friend. I'm with GiffGaff and the phone is locked to Vodafone. The contract on the phone has ended, and the only way I know to unlock it is via the Vodafone unlock service. People have told me my friend has to do this, but with their permission to use the details can I still do it myself? (Fill it in with their details, they have already said I can as they don't have the time)

I think i've already asked a similar question but just need to be clear, thanks!
PS, I DO NOT want to jailbreak the phone! So please no answers saying that it's the only way!

I'm looking for an iPhone app that I used to have?

It's a shooter/ defense game mix. Soldiers and vehicles/helicopters rush from the right toward your bunker on the left and you shoot them as they run by. Can't remember what it is called, but I want to play it again. Seems like I never want to play anything until the day after I get rid of it.
