Why is my iPhone text sound not going off?

I already checked all the settings. Could it be time for an upgrade? Probably so… And yes, its a 3GS i don't need any more crap for having an old phone i'm just using this one because my Mom just got a 5 and I wanted to see how iPhones work before my upgrade in a few months. Why is the sound going off on phone calls but not texts? Also when I go to plug in charger it doesn't make the noise it usually does and it could be because the phone is going. The speaker might be broken maybe? I don't know… Not sure whether to take to Apple Store because I hear they can't really help with 3gs or older model phones or maybe to take to my carrier… Anyone have ATT or know if they are nice about early upgrades? Please specify which iphone you have… Thanks. Please help! My friend who has a 4S was kind enough to help me in the meantime by placing on a loud repetitive vibrate so I don't forget about my texts because the volume is on high and the texts don't go off but the call sounds do? Sad face… Thanks yall

Added (1). Ok… Please give more details.how/why did it break and how did you get it fixed? LOL

Can an unlocked iphone 5 from America be used in Ireland?

So iphone's over here are really expensive and i'm going to America this summer and i was wondering if i could buy and iphone 5 when i'm over there. I would buy an unlocked phone but on the apple website it says "
The unlocked iPhone only works on supported GSM networks, such as AT&T in the US When you travel internationally, you can also use a nano-SIM card for iPhone 5 from a local GSM carrier. The unlocked iPhone 5 is model A1428. For details on LTE support see www.apple.com/iphone/LTE. The unlocked iPhone will not work with CDMA carriers such as Verizon Wireless or Sprint." I'm wondering will it work if i bring it back to ireland and put in an irish sim card? Anybody?

Can i change my current blackberry contract to an iphone4 (micro sim)?

Basically i'm on contract for a blackberry 9800 but i really want an iphone, my current cntract doesn't finish for another 7 months so what i'm wanting to know is would i be able to use my current contract simcard in an iphone? The issue that is confusing me is that the iphone takes a smaller sim card so is there any way of switching this? I know i can change my blackberry data to normal data but non of this will be any good if i can't switch to a smaller simcard.

Can an Iphone 5 with blocked IMEI be used in other countries?

Basically my brother has an iphone 5 for 4 months on billpay, but got a crazy high bill so didn't pay it and now no service. So phone blocked in Ireland I'm guessing. What I'm asking really is, if he sold it on ebay to someone in another country would the phone work for them as he doesn't want to burn anybody except the damn phone company

Cheers

Added (1). He's moving to Oz pretty soon so doesn't care about the phone company chasing him, and besides if a debt is less than 500 bucks its actually not even worth there while chasing it as wouldn't be cost effective, well cheers for the reply, at least he knows if he sells it on ebay the other person won't be buying a brick
